Error while running event Factorissimo2::on_built_entity (ID 6)
Factorissimo2/control.lua:765: attempt to index global 'factory' (a nil value)
stack traceback:
Factorissimo2/control.lua:765: in function <Factorissimo2/control.lua:741>

I was in god mode laying out how I want to do my oil setup in my real game. I was placing factories (I only used MK3 and I had all technologies researched) inside of factories. This crashed as soon as I placed one. But I don't think it was one too many factories, I had removed and replaced a couple times already with no issue.

Update on error: I wasn't able to recreate the problem, but I did get another error today:

Error while running even Factorissimo2::on_tick (ID 0) not enough memory

Ah, the first error looks like my mistake, fixed a bug wrong. The "not enough memory" error looks like you literally just ran out of RAM though.

Hi Magma

I am receiving the same error, any news on a fix?
Thanks for all your hard work and an awesome mod!!

Hi friends,

I found a method of reproducing this problem.
(1) Place 'Factory building Mk3'
(2) Go into the building
(3) Place 'Factory building Mk3' inside
(4) Witness error dialog

Here's the output that I got.

Thanks for this mod. I'm having so much fun with this. I'm still very new to it, hope I'm not doing something wrong. I read the FAQ but I don't see anything that states that this is not possible.

I'm running the latest version of Factorio "0.17.79" and Factorissimo2 "2.3.9".

Fixed.

Thanks a lot MagmaMcFry! You are awesome!
