Please i need help, for some reason the constellation paper became green, and i can't even know what are the constellations

Another mod is not cleanly handling its render code. You will have to determine which mod is causing thr conflict and open a ticket on their side.

I play on the modpack ftb academy and the problem start when i logged in, last time i played the problem was not there, if i create another world the issue disappear

Doesn't change what I said. It isn't AS causing the issue.

Most likely whichever mod adds the overlay on the right.

As was stated previously, this is most likely the result of the overlay on the right side.
