The mana spreaders from botania are not allowed to work in the claims for some reason. Is there a setting in the server's or player opac menu that can allow them to work in claims? This is an issue in a Vault Hunters 3 server that is running opac.

I came here to look for a solution to this, did you manage to find one? It seems like they might work in unclaimed areas, but that is far from ideal.

I can confirm the issue, and I can confirm that mana spreaders are working in unclaimed chunks. I tried unclaiming a claimed chunk containing a mana spreader, and it did not work afterward.

AFAIK, Botania uses "fake players" for some of their game mechanics and this may collide with the chunk protection.

Also having this issue. I found that un-claiming the chunk then rebinding the spreader caused the spreader to start working again.

Tried adding Botania to the staticFakePlayers field in the openpartiesandclaims-server.toml config file, but this did not work.

Found a workaround. Set the "Protect Blocks From Other" setting in the Default Player Claims config to off, then use Wand of the Forest to re-bind spreaders to destination. This allows spreaders to work as normal.
