Every time i start a game my whole Caravan/Embark transforms then subsequently fight each other to death, just breaks worlds

Few observations so far:

Trade caravans end up transforming and break trades

Clothes become a massive pain as the many different sizes introduced make equipping a fortress rather difficult - would it be possible to have the change happen less often, or have equipmentmaking be simplified?

They could die fairly young. You can remove them if you go into the file. There are some lines that say [CE_CAN_DO_INTERACTION:PROB:2

You can set the 2 to 0 to prevent those interactions.

will you release a version where they cant turn into necromancers or vampires?
