Hi!

Started a new game recently and got into automating trees with the harvesters, had this error show twice at seemingly random moments, but it seemed to be while the harvester was gathering.

Error while running event Cursed-exp::on_tick (ID 0)
Cursed-Exp/scripts/on_tick.lua:469: attempt to perform arithmetic on local 'num' (a nil value)
stack traceback:
Cursed-Exp/scripts/on_tick.lua:469: in function 'main'
Cursed-Exp/control.lua: 194: in function
<Cursed-Exp/control.lua: 192>

Game version: 0.17.68
mod version: 0.6.12

I'll post my mod list if required.
thanks in advance for the help and thank you for making such an amazing mod!
