Hey Quezler it seems that using this mod with your newsletter mod breaks it, in some scenarios this mod just does nothing, sometimes returns with:
The mod Space Exploration - signal transmitter new channel name suggester (2.0.1) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event se-signal-transmitter-new-channel-name-suggester::on_gui_text_changed (ID 2)
...nal-transmitter-new-channel-name-suggester__/control.lua:47: attempt to perform arithmetic on field '?' (a nil value)
stack traceback:
...nal-transmitter-new-channel-name-suggester__/control.lua:47: in function <...nal-transmitter-new-channel-name-suggester__/control.lua:45>

could you send me your savefile?

Sure:

to replicate: after clicking Change channel button it doesn't auto suggest surface name, it remains as Default, trying to change the channel's name from Default causes the error. Only occurs when newsletter mod is present.
