After updating from 0.1.9 to 0.2.1 I have the following error when loading my map (the map has been saved from a server before trying in single player with updates)

Error while running on_configuration_changed: LuaEntity API call when LuaEntity was invalid.
stack traceback:
beltlayer/configchange.lua:31: in function 'task'
beltlayer/configchange.lua:17: in function 'on_mod_version_changed'
beltlayer/control.lua:91: in function <beltlayer/control.lua:89>

Thanks for the report. I'll work on a fix.

I just saw you released another update, when I now update from 0.1.9 to 0.2.2 I get this:
(the game loads this time, but i get this error, and trows me back to the main menu)
Error while running event beltlayer::on_nth_tick(10)
beltlayer/Connector.lua:145: table index is nil

Can you try 0.2.3?

Thank you, 0.2.3 works fine (upgrading from 0.1.9)
