Eidolon Evolution and Synthesist
 

I’ve just made a bug report and thought it was worth mentioning here in case I’m missing something.

After adding the Ability Increase evolution, the Synthesist isn’t seeing the increased ability score when fused, just the base score.

EDIT: Just noticed that the evolution takes effect if you change your character, for example increase a usage usage counter, add item, check a condition, etc. But, if you deactivate the Fused Eidolon and then activate once more, it is back to base scores. I am guessing that there is a 'on character change' trigger somewhere in the code.
