Update! Somehow I don't think it was caused by the enchant itself. I tried doing some tests to recreate the bug. In the first few attempts, the armor broke instantly with the projectile protection enchant. So I was thinking: _this must be caused by that._ but I was dead wrong because it also immediately broke when i tried protection only. Then i thought: _maybe it's the blaze projectile doing it._ So i tried testing it with lower levels, like protection 2 only. But then the bug just stopped appearing. It was kind of weird though, maybe i might do more testing soon. I'll edit this comment again once I found the answer. EDIT! I FINALLY FIGURED IT OUT GUYS! The cause of the bug is the dispenser at the repair station. Somehow the enchant itself doesn't cause the bug, it was the dispenser and the fire charge that's causing it. Now I know what to update!
