Hey, so few hours ago my server just shut down after a server crash, and ever since its been crashing every 10 or so minutes.
Here are the errors from the log:

Now I have deducted, and correct me if I am wrong, it seems like a sapling is causing the server to crash every time a tick passes and its supposed to grow.
Now my suspicion is that this might be because of an old plugin (that I removed now) that would replant trees after cutting(burning) the tree although I have noticed the sapling created was not the same type as the tree cut down.
Any clue on whats up and how I can solve this other than a rollback?
