Quote from Fateofman
When I logged in without the stained glass mod, it just turned all of it into regular glass. So you could potentially play if you're willing to replace all that stained glass later.
This is assuming that what works for me will work for you
if it turn to normal glass then if u back to install stained glass it will turn into stained for its a damaged glass the maker of fancy pack used the same form that use the wood damage id to no use more id and with that it can work on online but not recipe
