It is a known issue that the particle that are attached inside the character animation is not working in BB 2.2.6. You can downgrade to BB 2.2.5 (so far the clean version after BB 2.1.1 in my opinion). And later can move to BB 2.2.7 when available.
Thanks for "particle attached inside character animation" because thats exactly my problem. And ok, I'm going to do a downgrade.
