I recently decided to have another go at trying RP-0, and downloaded a fresh install of KSP 1.2.2 from Steam. I then used CKAN to install, first, Realism Overhaul and its dependencies and recommended mods. After which, I installed RP-0, and its dependencies and recommended mods.
Once all installed, I tried launching from CKAN, and the game immediately crashed.
The crash log is contained within the following link
I then tried the same with the 32 bit exe. Instead of it crashing immediately, it instead crashed when it ran out of memory (I tracked how much RAM it used with Task Manager, it crashes when it reaches about 3.3-3.5GB)
There appear to be no other solutions that I can find for this error, and was wondering if anyone else has been experiencing this error, and if there were any fixes.
The mod list as exported by CKAN
These are the most up to date versions of the mod CKAN allows for 1.2.2
DxDiag - I have seen this be requested a few times in relation to similar crashes from other games, so will provide it.
Thank you for any help.
