Mod Version: 3.4.9.6

Forge Version: 2623

Link to crash log (if applicable): Crash Log

Description: Game startup crash.

Was Forge complaining about a mod dependency issue at the time of the crash?

No. Reverting to 3.4.9.5 fixed it.

The prior version didn't have this particular issue because it is new code that is being triggered. Would you happen to have the client log available? I want understand the context around the crash a bit better.

I should. Let me check and find the log.

And now it loads perfectly fine. I changed nothing other than the DS version. 😕 Gah. Errors like this are the bane of my existence as a programmer.

It's the particular nature of this issue. It appears timing related. The only time I have seen this issue in development is when Forge fails a mods dependency check. I suspect, though, that there may be mod interactions that alter the startup timing which triggers the problem. Regardless it is going to be fixed for the next BETA. :) Thanks!
