after version 1.0.4, an error occurs when loading the game

51.323 Error ModManager.cpp:1625: Error while running setup for entity prototype "sf-tile-bonus" (beacon): next_upgrade can't be set when flag 'not-upgradable' is set.

Thanks for the report, see if you can try hotfixing this issue by removing the 'not-upgradable' flag in the mod itself in the data-final-fixes.lua file.

After removing the 'not-upgradable' flag, another error appeared:
44.995 Error ModManager.cpp:1625: Error while running setup for entity prototype "sf-tile-bonus" (beacon): next_upgrade target (beacon-2) must have the same bounding box.

Do you have any other mods running or something that changes how beacons behave (like upgrades technology etc) or is this just vanilla since it's something I can't reproduce at the moment.

A large number of mods have been installed, but as far as I understand, only the mods of Angels and Bob affect beacons

Ok, I've uploaded a fix on the github (the blue source code button above) in the data-final-fixes.lua file, see if replacing your current file with that one works (you can also just copy paste and replace the code in your current file). Holding out on updating in case it breaks more stuff or it doesn't work.

at first glance, after replacing the code, everything returned to normal 👍
