Hey got an error when deleting the chest while an items was transfering:
error message:
The mod Orbital Transfer (0.1.2) caused a non-recoverable error. Please report this error to the mod author.
Error while running event orbital-transfer::on_tick (ID 0)
LuaEntity API call when LuaEntity was invalid.
stack traceback:
[C]: in function 'index'
__orbital-transfer/control.lua:331 in function 'handleOutboundDeliveryTick'
orbital-transfer/control.lua:379: in function <orbital-transfer/control.lua:366>

reproduction steps:
Place chests => request items => Delete chest while item is in transit
==> Error

Ah, I think I see the problem, I'm not checking for validity when I try and switch the item to the target surface.

I'll fix this for the next version (most likely today), thanks!

Fixed (hopefully, anyway) in 0.2.0, let me know if it happens again.

it happened again

The mod Orbital Transfer (0.2.3) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event orbital-transfer::on_object_destroyed (ID 176)
LuaSpacePlatform API call when LuaSpacePlatform was invalid.

weirdly enough its only happening on 1 specific plattform

and both chests are affected, doesnt receive or send stuff either

It could be that the current entity is bugged. Try removing it and replacing it.
