Description of the Bug
Every time the steam oven goes to play a sound when it finishes an operation, the client crashes with a NullPointerException. There are no errors, warnings, or other messages relating to Railcraft on the server console when the crash happens.

To Reproduce

1. Build a Steam Oven(s) as normal.
   2 Supply items to smelt (in my case logs, and steam (using TE steam dynamo for this)
2. Wait until the smelting operation finishes.
3. Client crashes with a NullPointerException. With VanillaFix installed, it just throws a toast message with a link to open the crash report instead of closing the game. I tried disabling FoamFix's coremod functionality, as well as removing SoundFilters, and the issue still persisted.

Expected behavior
Expected to hear a sound indicating that the smelting operation finished.

Logs & Environment

• Full log: https://gist.github.com/Questwizard/36c44a4949234cb83163627d83820a83 (note: full of spammed crash reports thanks to vanillafix)
• Crash report (If available): https://gist.github.com/Questwizard/078de056cb2545459b735849377e502e (this is one of many, many hundreds of identical crash reports as one gets generated for every furnace separately, for every smelting operation)

Additional context
This is on a dedicated server that I'm hosting myself. The server doesn't show anything at all in the log at the time of the crashes.

Disabling sounds in the mod config and restarting the client and server causes the errors to go away. I'm guessing it might just be a wrong sound name, or a missing file somewhere.
