Hello,

It doesn't happen every time, but while testing the mod, sometimes deconstructing the upcyclers causes the game to throws this error:

The mod Upcycler (1.1.7) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event upcycler::on_tick (ID 0)
LuaEntity API call when LuaEntity was invalid.
stack traceback:
[C]: in function 'index'
__upcycler/scripts/tick-handler.lua:48: in function 'update_struct'
upcycler/scripts/tick-handler.lua:132: in function <upcycler/scripts/tick-handler.lua:123>

let me know when its reproduced reliably from an autosave

My apologies, it seems the bug was in an interaction with the Creative Mode mod. I had the instant deconstruct option on and that seems to cause the bug. When using the decon normally, it seems to work.
