188.548 Error MainLoop.cpp:1202: Exception at tick 22888355: The mod Powered Belts caused a non-recoverable error.
Please report this error to the mod author.

Error while running event PoweredBelts::on_tick (ID 0)
PoweredBelts/control.lua:76: bad argument #1 of 2 to 'next' (table expected, got nil)
stack traceback:
[C]: in function 'next'
PoweredBelts/control.lua:76: in function <PoweredBelts/control.lua:74>

I don't have any made yet, so it looks like your check for whether that table exists doesn't work.

Should be fixed, can't test because it doesn't happen for me.

Will test when I next load.

Well, it doesn't error anymore! Haven't tried using any belts yet.

Glad to hear.
