[Susuy]

most of the time the problem happens when the player is in the antharas lair region, after killing the monster the player goes back to level 1 losing all skills

I have some but they are all in the datapack, they are custom items. I already applied the diff, I'll put it online to test thanks

[Mobius]

Any news?

[Susuy]

Sorry for the delay, so far the problem has not been repeated. overflow, as few times waiting in all these months can take a while. ate now the player did not complain again.
