Unable to Complete Charactermancer

I have had this problem for some time. I can go into the Charactermancer, and I can fill out the character, but if I try to "Apply Changes," it resorts to an endless load, where it claims to be uploading the character information but never actually moves at all. I have tried reloading pages, changing character names, and many other methods, but there is no way I have found to solve it. As is, the situation renders making a character for a campaign impossible.

I'm having the same problem. I have had it before too. There are some class/feat combinations that break the charactermancer. The way I fixed it last time was to manually add components I felt may be the issue. Usually the trigger is something that has a secondary choice in it or a manual entry in a field. In this case it was fey touched making me pick a stat and spell, that broke it. I changed it to actor and then manually added fey touch and dissident whispers spell and the charisma boost and deleted actor.  I have also had it break on adding a second favored enemy for ranger. So I just skipped it and added one manually. Look for things like that. I have heard there is an update to the character sheets that's causing some grief too, its definitely a lot slower now which is a step in the wrong direction.

That change on the feat did the trick. Thanks!

This happens constantly to me - so far I've run into a dozen different scenarios. Most recently, charactermancer HALF detects my multiclass - it knows its there, does my spells, but all the features, etc never get added.  It's a mess really.

Fey Touched definitely breaks charactermancer. A player of mine had the same problem. 

For me it was Shadow Touched. But the fix worked.
