On start i get the message: Failed to load mods: Error while running setup for entity prototype "space-solar-panel" (solar-panel): next_upgrade target (solar-panel) must have the same bounding box.

Can you please give me your version that you're currently running and possibly a link to a screenshot of the error.

the error message i got was
"Failed to load mods: Error while running setup for entity prototype "space-solar-panel"(solar-panel): next_upgrade target (solar-panel) must have the same bounding box.
Mods must be disabled: * Space-Block-DLC (1.0.11)"

i managed to get it fixed by disabling squeak through (or any other mod that changes building bounding boxes so you can walk between them (in my case it was actually Exteros' QoL System))

oh that makes more sense I ended up having a workaround by adding the space suit in the latest update but it's not accessible in previous saves.
