That's a good question, I just came here to clarify that exact thing!

I don't use camp casting shenanigans. Edit: which would certainly not work with ANY concentration spells.

I just tried this again with the casters using these spells on their own weapons and it's the same result. I believe this has been cast on 5 different weapons among 3 different party members. And that's just this testing right now. I also noticed this is in my last game but these spells were not essential so I just avoided them or considered them to be per-combat or per-Short-Rest.
So this has happened A LOT.

I literally don't have ANY other concentration spells, since the build of this party was maintaning concentration on Elemental Weapon and Magic Weapon at all times.
However I did have Haste from an item and I tried that, and it carried over just fine, losing 1 turn of duration ticking from 10 to 9.

Unequipping the weapons does not end the spell, nor does trading them. So even if the spaghetti code were un/re-equipping them, that wouldn't be it.

I know the wiki somewhere explains something about zoning changing player states and resetting Long Rest stuff (giving you back charges), so I had assumed this is somehow related to that...but why just these spells? It is NOT "refunding" me these spell slots. If that were the case I could just cast them fresh every combat.
