I've tried adding it to a new run of Space Exploration with the new 0.7 version and it crashes on launch:
Failed to load mods: underground-pipe-pack-simple/data-updates.lua:188: attempt to index local 'tech' (a nil value)
stack traceback:
underground-pipe-pack-simple/data-updates.lua:188: in function 'add_tech'
underground-pipe-pack-simple/data-updates.lua:262: in main chunk
Mods to be disabled:
• underground-pipe-pack-simple (2.0.2)
Line 188 is this:
local tech = table.deepcopy(data.raw.technology['foundry'])
Adding a guard on line 262 to only add this tech when space-age is enabled should work to fix it:
if feature_flags["space_travel"] then
add_tech()
end
But I'm seeing some metallurgy related stuff later on, so it's possible more modifications are required to make it fully compatible with SA-less Factorio.
