While not 100% sure this is the grimm press polymorphism, see attached below, i think it is.. ( If not I dont have the one you are using, can you provide some screen shots. )
Attachment 53222
I did a quick configuration and changed an NPC and a player with the extensions and all seemed fine without out.
I dont use equipped effect so maybe a configuration of that might start to generate the issue.
Could you provide more information, test on a clean campaign with just these couple of extensions enabled... to try and see if its a more complex extension conflict that we need to track down etc..
at the moment I dont have the information required to replicate this issue, so further details are needed. ( Feel free at attach a campaign zip into the forum, or DM me a dropbox type link if you have privacy issues... or create a clean test campaign you can attach etc.. )
Thanks, Pete
