Ok, this little hotfix patches one more annoying crash bug and finally should make your game quite stable. This bug fixed with 3.0.5a was even present in the final version of 3.0.0, but for some reason didn't occur that often until the release of 3.0.5. Took us a long time to figure it out what it was. In case you wonder, the ingame menu still says 3.0.5. Not much else to add here. Have fun
