Cargo Containers from Stockalike Station Parts Expansion Redux mod (2.0.5) seems ignored by SimpleLogistics (2.0.5.0) on KSP (1.12.2).
I would share some Ore between 2 landed factories. These parts content are not display in SL UI. Squad Ore parts are OK.
Any patch I could apply waiting an improvement?

@SylvainLasnier thank you for the report!

Are the SSPx containers attached to a vessel? Does that vessel have a part with [ModuleCommand]? (aka a pod or drone)

Any vessel with at least one [ModuleCommand] and has SimpleLogistics! (SLOG!) installed should register all resources from all parts (except for ones that are on the 'blacklist' like [solidFuel])

The exception MIGHT be and I will look at it more when I do an update pass on SLOG! (near future) is the resources are hidden within the B9; however since SLOG! directly queries the vessel for its resources - that should not interfere.

When I find time I will create a copy of the game, install SSPx, B9, and SLOG! and see if is reproducible.

More news when there is new.
