I finished mech quest and customization station, fuelling tab and loadout tab said unauthorized user

I have a similar issue. It unlocks when you first complete the quest but then once you teleport out of the area it makes them unauthorised again

I see the issue now, seems like the new update broke more things than i'd seen, working on a fix right now, thanks for reporting!

the fuel tank upgrade doesn't work, it'saccounted for in the fuel bar darwing function, but not the actual fuel max function, somehow, you can't ever fill the extra fuel part

this mod broke the mech quest, ropes, and tech for me, unsubbing fixed it

Hmm, looks like one my patches broke something, gonna release a fix soon, thanks for the feedback!

I'm getting a minor bug with the mech beacon marker showing even when deactivated and not piloting

Another minor bug where the first mech test drive has to be abandoned due to not having any mech fuel
reentering the quest afterwards fuels it fully and gives some extra 59 mech fuel on the side

I'm aware of that bug for some time now and have never been able to fix it, mainly because for the life of me i can't seem to replicate that.

There's a bug with the "NPC Mechs" mod, it tries to fuel the mech when it has less than 25% fuel and in your mod, in "modularmech.lua", where it says:
"--XS Mechs -- NPC Mechs compatbility
if self.driverId ~= self.ownerEntityId then
storage.energy = 100
end"
And becaus most mechs have more than 400 fuel, it means it's always at les than 25%.
I have made a patch while people wait for the fix.

Hmm, i didn't know about that, my bad, should have used the max value for fuel instead of a fixed 100, gonna release a patch soon.

when first loading into the mech after completing akkagy's quest to gain it and further uses, it doesnt show how much fuel you really have untill you pick up something that gives you fuel.

Cant use the expansion slots. I got cosmetic mechs. Also not really compatible with FU since FU also ads fuel

This mod is practically in FU. The items and fuel types are the same with some minor changes and additions from FU.

i unistal the mod and is still have a effect on my game
