Aternos crashes when trying to join the server

I have a modded Java server, which worked fine until now. I haven't changed any mods or anything, the server just crashes seemingly out of nowhere when i try to join it. I don't really understand the crash logs and I would really appreciate if someone helped me.

Here is the crash report: https://mclo.gs/eSq3Rct

ig a block/entity hose pulley is corrupted and ig it belongs to the create mod. try removing that mod and open the server

Well, I could do that, it's just that I'd probably lose all my create mod contraptions. Thx for the suggestion
