I told you the german language mod is
just for TWoS 1.05 + update 0.7!
When you are running actuall TWoS update 0.8 with the GL mod a unstable game could be the consequence.
Iam not using the GL mod at the moment because i want to have a "clean" game with using the TWoS mod 1.05 + update 0.8.
Anyway, i recommend you to use the current version of TWoS + update 0.8, playing in english or using update 0.7 and playing in german if you want to.
