I have the same issue on 1.20.1. It appeared when I found the blood feeder's home. I'm a vampire if that matters. Soon after walking in the forest, the game crashes. When I reconnect, I can explore for a few seconds to a few minutes before another crash. My log has the same concurrent modification error. I play on a modpack based on the first Neoforge (forge 47.1.106) on Minecraft 1.20.1. My Vampirism version is 1.10.9.

From the log file I can not tell what the problem is. The errors are just errors in other mods implementation, but shouldn't cause this crash.

The issue's description does suggests that there is something at fault in Vampirism. But it will be hard to find.

As Leiriad already figure out (Thank you 🙌 !), this appears to be an issue with other mods as well. (based on above crash-report)

It is not entirely clear what is causing this and if Vampirism is at fault here.

In the ATM issue somebody posted an workaround mod, to replace that list with one that is able to handle concurrent modifications.
AllTheMods/ATM-9#406 (comment)
Unless you have some idea what Vampirism might have to do with this (@Cheaterpaul ), we could also consider adding this workaround and replacing the map (if it wasn't already).

I am not sure what the title of this issue has to do with the content...
Please let me know if there is something I am missing

fixed in the latest version
