So I was flying in a cargo rocket from one surface to another and it suddenly outputted a warning into the console(see image https://imgur.com/a/6Vl5JEn).
The server admin said that it streamed more than just the two warnings into his console:

84732.290 Script @stdlib/stdlib/core.lua:45: PickerInventoryTools:PickerInventoryTools/scripts/chest-limit.lua:16: attempt to index local 'stack' (a nil value)
84732.291 Script @stdlib/stdlib/core.lua:45: PickerInventoryTools:PickerInventoryTools/scripts/chest-limit.lua:16: attempt to index local 'stack' (a nil value)
84735.823 Script @stdlib/stdlib/core.lua:45: PickerInventoryTools:PickerInventoryTools/scripts/chest-limit.lua:16: attempt to index local 'stack' (a nil value)
84735.842 Script @stdlib/stdlib/core.lua:45: PickerInventoryTools:PickerInventoryTools/scripts/chest-limit.lua:16: attempt to index local 'stack' (a nil value)
84735.856 Script @stdlib/stdlib/core.lua:45: PickerInventoryTools:PickerInventoryTools/scripts/chest-limit.lua:16: attempt to index local 'stack' (a nil value)
84735.876 Script @stdlib/stdlib/core.lua:45: PickerInventoryTools:PickerInventoryTools/scripts/chest-limit.lua:16: attempt to index local 'stack' (a nil value)
84735.942 Script @stdlib/stdlib/core.lua:45: PickerInventoryTools:PickerInventoryTools/scripts/chest-limit.lua:16: attempt to index local 'stack' (a nil value)

Ive tried recreating it on a local copy of the server map, but cant seem to do it.
Probably has to have something to do with the Navigation View Space exploration has, that lets you dis-embody yourself and look around the map as a player ghost, cause you cant access inventories if you arent in that view while flying in a rocket.
