Occasionally when joining a server I get this error message.

[BanishedLetters]

Only option it gives is to hit OK and then Blockland shuts down. Rejoining the server fixes the problem, but I want to know if I can prevent it from randomly shutting down.

My brother has a mac, he comes down to visit with it and sometimes I play blockland on it, I get that message too, rarely.

It is cache.db. Delete that file.

It is cache.db. Delete that file.

No. do not do that just yet.

First step. Change permissions for the cache.db file.
If that doesn't work, then rename is cache.db.old(?)

If neither of those work then post console.log
