Hey there! Thanks for the mod.

I unfortunately get this error on startup:

Error ModManager.cpp:1560: Error while running setup for entity prototype "water-miner-1" (mining-drill): next_upgrade target (water-miner-2) must have an item that builds it that isn't hidden.

I have these mods active, and my guess is that it broke with the recent Bob's and Angel's update. It happens too with the full modset, but I narrowed it down to this minimal subset. Note that removing any of angelsrefining, bobores or bobmining actually starts up fine, so it's the combination of the three that causes the issue.

angelsrefining 0.12.3
boblibrary 1.1.6
osm-lib 1.1.40
bobores 1.1.6
bobmining 1.1.6
P-U-M-P-S 1.1.67
angelsrefining 0.12.3

definitely on my end

i'm unable to replicate, going to need a savegame

I'm having a similar issue, it happens when loading the game, not a save.

Try update osm-lib
Also "i'm having a similar issue" is vague at the very least

Updating osm-lib to 1.1.41 fixes the issue, thanks!
