Reproduction:
use wind charge item: it shoots a projectile that is the same as breese's projectile
use fire change item: nothing when not looking at a block, set the block on fire otherwise
Expected result: fire charge item should fire a ghast projectile
Actual result: different behavior
It will be a glorious day when fire charges can be thrown as a projectile. Until then (and afterwards too) please leave feature requests on the Feedback Discord and not Mojira. (But don’t make a new post for throwable fire charges, just drop an upvote on the existing ones.)
