When i try to play with my friend splitscreen and he joins if any addon is active the “new” blocks it adds become glitched and invisible instantly and there is no way to fix them by reseting world or clearing cache, i noticed the issue is present in all addons that have blocks that arent in the original game, mobs and structures seem unaffected only certain blocks
