All skill effects seem to be lost on Game restart and reload. I have to reset skills and then reapply them for the effects to take place again. Example I lose all the efficiency recipes access and smelting productivity.
Cant seem to replicate on just restart of game might need entire PC restart.
2nd bug is Ming Productivity seems to be gone from research from this as well as im on mining prod 6 after the restart and only have 125% after that completed after I was at mining prod 5 before PC restart
Turns out there was a tonne of underlying bugs from this one, so thanks for brining it to my attention. Looking at it now and should be fixed in the next version.
