Electrosynthesis

Echoing the drag issues another user mentioned a few months back. From what I can see using the aero debug tool and F12, procedural fairing bases don't have any drag occlusion area. The game ends up thinking that anything attached directly beneath the fairing base is completely unprotected from the airflow. Usually that's a fuel tank with a flat top, resulting in very high drag and an aerodynamically unstable rocket. I haven't tried it with FAR as I'm not familiar enough with that mod to interpret the numbers.

@JebNotFound Better Time Warp can't do thrust during on-rails timewarp as it just changes the warp rates you can use, but not any of the game mechanics. There however two mods I know of that *can* do what you are asking. 1. Persistent Thrust Extended adds the feature for all engines, but there may be incompatibilities. Best to check the forum thread for the latest status. https://forum.kerbalspaceprogram.com/index.php?/topic/194707-1711811911101-persistent-thrust-extended-175-now-with-background-persistent-thrust/ . 2. KSP Interstellar Extended includes an implementation of persistent thrust for the engines it adds or has modified. It's a really big and complex game overhaul mod, though, so you probably wouldn't want to install it just for that feature alone. https://forum.kerbalspaceprogram.com/index.php?/topic/173818-181-1122-ksp-interstellar-extended-1295-release-thread/ . Hope that helps! Edit: worth adding - as far as I know there aren't any implementations of persistent thrust that work with Principia

Aha! That's it! Nuclear fuel transfer is working when that option is off, and not working when it's on. Regular fuel transfer is working as expected in both instances. Here's a screenshot of my test craft (only NFE and System Heat installed here). I don't really see how crossfeed rules should prevent this transfer, unless I'm drastically mistaken? At any rate, as far as I'm concerned it's problem solved. I can just turn off that setting and get on with things. Your help and patience is much appreciated! Thanks once again for making these awesome mods, my main save is practically Nertea Space Program at this point

I've tried it of course, but you might be onto something here. With KSP running on Linux, RShift replaces any use of Alt. e.g. the cheats menu is RShift+F12. Completely guessing, but perhaps the game process can't receive the Alt keydown signal for some reason, forcing the devs to use a different key. Is it possible this is the problem @Nertea -- some code listening for an Alt keypress it will never be able to receive? Please believe me though, I've tried every combination of clicking I can think of - right, left, Shift, Alt, RShift... . There are simply no fuel transfer options showing up anywhere for these nuclear parts.

There's no UI option for that either

Yep. I have a level 5 Engineer in sandbox mode. These were my testing steps if anyone wopuld like to try reproducing it: Back up, then delete KSP game directory. Redownload fresh from Steam. English localization. Install NFE and any required dependencies via CKAN (I made sure not to add any optional/recommended mods, only the strict requirements) Start KSP, begin a new sandbox game, and design a craft. Craft has 2 nuclear fuel drums, one empty and one full, and a pod with a 5* engineer Launch the craft and confirm the transfer is working Close game and install system heat via CKAN. Include the 4 system heat config packages (engines, reactors, converters and harvesters). As with NFE, required dependencies only, no optionals. Start KSP, reload the sandbox game, launch the exact same craft with the same kerbal. Observe that the fuel transfer option no longer appears in the UI. I was quite careful with the whole process because I was trying to discover which mod in my mod list was causing the problem. Took a while - System Heat wasn't high on my list . By the way, I am running on Ubuntu 20.

Hi Nertea, thanks for making this great mod, I'm really enjoying it. I'd like to report an incompatibility with Near Future Electrical. When both are installed, I no longer get the UI option to transfer nuclear fuel between containers. Tested on a fresh install of KSP 1.12.2 with only NFE and System Heat installed (plus any required dependencies according to CKAN). I saw in a previous patch note this problem might depend on localization - I'm using English. Hope that helps!
