I acctivated to try it, but now all my villager don´t have limit at trading

thats intended? are u trying to say u disabled it but it still is effecting ur villagers??

The current implementation of the tweak is rather bad, and it causes the modified values to get saved to the NBT data of the villagers. I should rewrite how it works so that it wouldn't touch the saved data in any way.

As for the villagers that are currently affected by this, I think the only way to fix it is by using an NBT editor. But I don't remember exactly what it does currently and which value it changes, so I'd need to check that. I think either the current trade use count or the max trade use count gets increased beyond its normal limit in some way.
