@LunaMoo that is interesting. The commit (combined with the 2 hacks and GE2 v1.40) that sort of fixed the consecutive missions was somewhere between v0.9.8-695-g8c11559 and v0.9.8-826-g4873c5c.
The chinese is based on v0.9.8-695-g8c11559 combined with the 2 hacks, and that one doesn't seem to work with consecutive missions.
Your build is based on v0.9.8-826-g4873c5c combined with the 2 hacks, and that one does mostly work with consecutive missions (although there is a severe speed issue with every other mission).
If the right commit is narrowed down it could probably be improved.
