Do you have dimensional threading installed?

Same here, I havent added anything more other than Canary to server side and Fable weapons + Embers mod

Thank you. I don't think Canary or Fable weapons should cause this.

Post a log of your issue and I'll see what I can do. As for the OP, this is how I know Dimensional Threading was present in their game:

[dimthread_server_dungeon_dimension/ERROR]

Dimensional Threading isn't a good mod. It says that it is incompatible with several major mods, such as Create and AE2. But really it is incompatible with any mod that sets a block state anywhere. Which is just about every mod! The author of a certain fork then blames every other mod developer and says we should all write thread-safe code. But there is no threading without Dimensional Threading in the first place! It is impossible for other mods to comply even if we wanted to.

Soo, any info about it or potential fix?

I think I have find an issue here
Soo I started to test out dimensions on Single world and all was good, I've made more than on server and no isses

So I went back to on server to see if the portal that my friend build in her house affects my one somehow, but she removed it soo thats not is...

I went back and started to test out all the keys I have crafted and found in Dungeons, all of them works except for 2 I've made but there was one I have never used and it worked soo I crafted one more key and rolled back to end portal to activate.

Turns out its working fine!...
Keys that dosen't work for me are named "Key to the Crypt of Inspirationa" and "Key of Happiness and the Past"

Note: While writning this, Ive got another key for nether dungeon and it's working fine
