The new 2.1.0 version causes a crash upon loading a save that worked previously fine:

Error while running event map-tag-generator::on_configuration_changed
map-tag-generator/map_tag_generator/init.lua:68: bad argument #1 of 2 to 'pairs' (table expected, got nil)
stack traceback:

Thanks for the report. Can you send a list of mods you're using in your save?

Sure!

Thanks! Looks like the issue was related to Carna doing some unexpected things with agricultural towers. The crash should be fixed now, though the agricultural tower logic is still a bit experimental and only really tested with default Space Age, so let me know if you notice anything else unexpected happening.

Will do, thanks for the fast fix!

Hey tried the new version today, got another error:

The mod Map Tag Generator (2.1.1) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event map-tag-generator::on_configuration_changed
map-tag-generator/map_tag_generator/init.lua:67: attempt to index field 'autoplace_specification' (a nil value)
stack traceback:
map-tag-generator/map_tag_generator/init.lua:67: in function 'cache_soils'
map-tag-generator/map_tag_generator/init.lua:111: in function 'update_compatibility'
...ag-generator__/map_tag_generator/event_handlers/init.lua:22: in function 'on_configuration_changed'
core/lualib/event_handler.lua:112: in function <core/lualib/event_handler.lua:109>

The mod list is pretty much the same.

Thanks again! This time it was Maraxsis :P I've reworked the logic so it should be more compatible with any unique things other mods do with agricultural towers, so hopefully it's more future-proof now.

Cool! I'll give it a spin one of these days, Ill report back if I see anything wrong. :)
