Hi there!
Got this while trying to use /alerts mute, because the flashing alerts (no electricity) where visually impeding me in Blueprint Sandboxes (tried to make space platforms, what more can I say). Let me know if I can be of any help.
The mod Helmod: Assistant for planning your factory (2.2.7) caused a non-recoverable error.
Please report this error to the mod author.
