Sorry to come back with another thread so soon after the first, but got another error on launch, this time from this mod:
https://mods.factorio.com/mod/Factorio-Tiberium

In data-final-fixes line 89, "no bonus order for ammo category obelisk"
The obelisk is a big laser turret basically, it uses power to fire and gets bonuses from laser research but has its own ammo category separate from lasers. Looking at it in the factoriopedia, the obelisk ammo category is in the misc tab, along with a couple of other things from that mod that seem to be in the wrong place. May be an issue that mod should fix instead? It has its own "Tiberium" tab, so it'd make sense to move the ammo category there.

Here's an image of the full message:

So sorry, I really shouldn't have left that check in the code, I only put it there to check that I gave a proper order to every ammo categories 'bonuses'. But if mods are going to define new ammo categories, I'm not going to try and guess what order they should have...

I've uploaded a new version of the mod that should load now without any errors, it instead just prints to the log file.
So if I could have your factorio-current.log after you usefully load my mod, I can see if there're other changes I should make.

Seems to be working well now, launches fine and there were no other warnings or anything in the log file!

Got a new error after updating to 0.6.0:

"Ammo category obelisk does not have an order set"

Woops, so sorry. I left debugging code in again! I've deleted it, and hopefully won't re-add it in the future.
