Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - Bugs & Technical Problems [BUG] Eternal artifacts boost is not permanent (?)

1) When combining the eternal artifact that gives air damage + shocked chance, the shocked chance boost ist gone after you load the game again.
2) Similar for the other artifact. I combined it with a neckless to get crit change, dodge and fireresist. I think this persisted longer than a single load, but still is gone now (maybe it vanished when moving from nameless island to arx?). I can not combine the same neckless again with an artifact to get the boost back. For some reason my boots, that received thievery, still have thievery although I have them since reapers coast. So I can't tell how to reproduce this bug.

Game version 3.6.33.2684
