Problem Players in Mystcraft Worlds Crash when Joining [Direwolf20 v5.0.1]

[Joey19982]

I just updated my server to the new modpack version, and been having a big problem.

Any user who isn't in the overworld (I don't know about nether or end) gets their launcher crashed with this error when logging in. Note this is a client crash, not a server crash. Here is the server log when disconnecting.

I already fixed the issue where Twilight forest was taking Dimension #7 by switching it to Dimension #400, and again this only happens to people in Mystcraft worlds. Anyone in overworld is fine.

I suppose they're just going to ignore this issue that is effecting a good amount of servers, including my own? I assumed they would have tested for this kind of staggering bug before releasing it, but it looks like the people that put together direwolf or direwolf himself are blithering idiots?

java.lang.IllegalArgumentException: Could not get provider type for dimension 27, does not exist

I presume dimension 27 is a myscraftage. As PrinnyCastGrover pointed out the majority of the servers are having this problem due to the addition off twilightforest.
Whats causing it / a fix for it is unknown atm.

Currently at work myself so can't test it to see if i get the error on my server / testserver or ssp won't be home till 1730 CET.

Disabling TF fixed the issue on my server. no one had used it yet so it wasn't a problem

Edit to clarify .. it needs to be removed from the server .. not just client side as the server wont let you login if its still there.

You can Disable TF, or delete the agedata.27 from your datafolder in your world folder.
