The Hidden Forest

Running ROF2 and the MQ2 from MQEmulator.
Everything was working fine with no issues, then I made a ranger.
I have the castingbuildermulti.mac that I obtained a few years ago and attempted to run it on the ranger and the client crashed. Tried reloading he kept crashing, gave up to try again today.

Now any character that loads in closes the client as they attempt to enter world.
If I don't load MQ2 at all everything logs in and works just fine.

I completely removed that MQ2 folder and made a new one with nothing in the folder except what comes in the zip file. Now the client doesn't crash it just sits there on a black screen after selecting entering world.

Any thoughts?

Haven't figured it out but narrowed down the source, for sure something in the MQ2 folder was wrong.

Loaded a fresh client and logged in with new client and MQ2 folder everything worked. Went back to my THF client I use all the time and everything works.
