Provided is the screenshot of the crash error and what I was doing to cause the crash (Adjusting the number of machines), aswell as a pastebin of my factorio log. (Should include any and all mods)

I was not able to recreate the crash, can you upload a zip of your mods folder?

Thats a carbon copy of my mods folder, I currently have ACT disabled due to the crashing. I'm pretty sure I cleaned the folder of all unused mods other than ACT.

hmm, I still haven't reproduced a crash using those mods. does it only happen in multiplayer games or both MP and single player games? perhaps you could provide a save game for me to try? can you narrow the list of mods down - remove a mod and see if the crash continues or not and repeat?

Alrighty, I'll get to work on some crash testing soon, as for the more info; It crashes both during multiplayer games and single player games. I can provide my save but its rather large and we've not had ACT enabled for some time. The crash was also happening when using ACT on the "Bio-Farm" and "Bio Nursery"

Fairly sure I know the problem, it's an easy fix but I'm away atm. Should have a new version out 24-36hrs

let me know if v0.2.9 causes any issues
