There is some issue with exoskeleton name Unknown key: "equipment-name.exoskeleton-mk2-equipment"

i cannot reproduce it

May by it is I use Russian language... but other things work correctly.

With this update, the TG Generator and personal battery appeared in SE, but exoskeleton and power armor disappeared. Is this how it should be?

Now the personal accumulator MK2 in SE appears later than MK3 and is equal in strength to MK4.
And the portable nuclear reactor (MK 1), in general, does not appear in SE as the analogue is called differently in SE, i.e. I cannot make MK2 - MK8, because I do not have MK1 in the recipes.
Let your equipment be available on a separate branch, without reference to analogues in SE, as it was before.

o well i don't have files for any other language, but normally it should fall back to english I suppose

I can give you a save to check, but I don't know whether you need it.

If you replace the last two lines in en/locale.cfg with:
night-vision-mk2-equipment=Night vision Equipment MK2
exoskeleton-mk2-equipment=Exoskeleton MK2
then everything becomes normal with the names.

But the personal power armor from your mod disappeared in SE. Everything else from your mod is now available in SE.

oh thats why because one locale is right and other 3 wrong

Now everything has worked as it should. Thanks!

thats nice
