Hi again,
i tried many things in the last hours and i solved the problem at the moment.... i removed every equipped spells and then no more connection issues in multiplayer

i know its weird but i have tested some spell combinations and this is my result:
Spell 1 equipped -> work fine
Spell 1,2 equipped -> work fine
Spell 1,2,3 equipped -> crashed like before
Spell 1,2,3,4 equipped -> crashed like before
Spell 1,2,3,4 equipped and then removed Spell 3 -> work fine
With the last combination it is possible to hold 3 spells... if you relogg, the fourth Spell will be displayed as third spell, but its only the drawing routine that draws all Spells without regard to order (i can only imagine that this happens). Anyways, we play mp in the next days and i will report our experience with the Theolentist. Thank you all for these awesome mods and the hard work you all spend to get them updated.
At least i have one question: Is it possible to change the steam Version of Variant Classes with the actual Torchmodder Version ? If i change them i got the info that my character needs variants (steam), the version on torchmodders is called variant classes. Do you have any ideas/advices how i can change them ?
Ty all !
