Hi, I've been getting an issue that was brought up earlier in the thread with staging. When I press spacebar it only activates one section of a stage. The problem is fixed when I remove KerbalJointReinforcement although it may not be the cause of the issue but might trigger it. This came out of nowhere, I haven't installed any mods recently and when I went to launch today it occured. Here is my output log: https://www.dropbox.com/s/4rk1czkr74f5bnx/output_log.txt?dl=0 Running .25 32 bit (waiting for certain mods to be updated before I go to .90) Here are my mods (says I don't have permission to insert images?) http://i.imgur.com/oSMKa5I.png I'd appreciate any help, the game is unplayable without the mod (works wonders) but it's also nearly unplayable with it/ or the conflicting mod causing it. EDIT: I seem to have missed several replies on an earlier page about this. Sorry for restating what has been said. I will make a clean install and try to narrow down the conflicting mods. EDIT2: I think I narrowed it down not to a specific mod, but a part in my case. I created a rocket like so: Taurus HCV XT2 Solar Panel Array mk2 Procedural FuelTank Fairing Base Ring (Procedural Fairing part) Procedural Stack Decoupler Procedural Fuel Tank (13 m Diameter, 32 m Length) Launch Clamps 5 F-1 (Realism Overhaul version of the "new" 3.5m stock engine) Total weight: 3,404,671 kg (some users, including myself, only encounter this on large rockets such as 1000+ tons) I first tested the rocket with only a probe on top and successfully launched and decoupled the launch clamps as normal. I went back an added a subassembly of a pod with the parts listed above and attempted another launch. Launch clamps came off 1 at a time. I then removed parts one by one until the problem was fixed and it happened to be the Procedural Fairing Base. I will do more testing and see if there are any other conflicting parts or try to determine what triggers this. This testing was all done with the mods in the pic above. EDIT3: After more testing, removing the fairing base ring always fixes the issue. One thing worth noting though is I am placing the capsule through the subassembly menu when the launch clamps fail. I removed the base and added a new one and it seemed to work. Anyone else having this issue also using procedural fairing bases or subassemblies when encountering this? Regards, James
