Hi

I was able to play Rimworld yesterday with the new DLC (have Royalty, ideology and Biotech]. No Mods.
Today when i started the game it fail to start.
no updates as far as I know happened on system.
Have Uninstalled and Reinstalled did not work

Getting the following Error message: see full attachement

Seems it is now working now

Had to delete the folders on: Uninstalling and Reinstalling did not work first time.
Home/.local/shar/Steamapps/common/RimWorld/
Home/.config/unity3d/Ludeon Studios/RimWorld by Ludeon Studios

Spoke to soon

When my PC Restarted now.
Got the same error again when trying to run Rimworld.

Error:
RimWorld 1.4.3524 rev757
Caught fatal signal - signo:11 code:1 errno:0 addr:0x7f0db95ae7b0

I have not had that in 1.4, but looking at logs I have had 6 cases of signal 11 in 780 logs, all in 1.3 early versions.
Usually it was when the RimWorld window lost focus right after starting. I always play in windowed mode.
Mods loading is threaded now, so there may be extra interesting things happening.
