Issue details: Trying to open sound settings crashed the client. Trying to open sound settings through the main menu or in game crashed the client.

We tried playing "Which one is it" by disabling all mods and re-enabling them one by one. No dice. I posted to r/feedthebeastcrashes and the advice I was given was to delete my options.txt file, which did fix it, they also said the issue MAY be related to Electro Blobs wizardry. We've since removed your mod and haven't encountered the issue again... Don't know if it was a one off and deleting options.txt was the solution, but multiple people had the issue. It's a custom pack so I'm assuming there was some kind of clash?
