When Telelogistics and Factorissimo are loaded together, Telelogistics attempts to insert into the surface_conditions table of its container prototype during data-final-fixes.
As it turns out, your "Allow Chests In Space" option deletes surface_conditions entirely from all container prototypes in data-updates. Since S6X didn't think he would need to nil-check his own prototype, this results in a crash.

I'm aware he could add a check on his end, but this seems needlessly destructive to me. If not anything more specific to the gravity property, at least setting it to {} rather than nil would still work fine, while leaving the table in place.

I chose to delete surface_conditions entirely because that way it falls in line with every other entity defined in data.raw - that is to say entities that have no surface conditions defined do not use {}, they simply do not have it defined.

I wasn't thinking of mod compatibility when I made that decision though, and I will likely change it the way you suggest for that reason; even if that does make it less in-line with vanilla's definitions.
