ToME: the Tales of Maj'Eyal

I tried to start an undead tinker.
They have the healing and water salve, but they do not start with any implant (neither injector, nor steam generator), and whenever you try to activate a salve there is a lua error (because of the lack of injector).
Obvioulsy it is a bug, but I do not know if it is because of the lack of implant at birth, or if they cannot use implants and they should not be allowed to be tinkers.
In terms of lore (or of physiology), I understand that nature items like infusions are forbidden. But I see no reason to forbid technology.
So my question: are undeads allowed to be tinkers and to use implants?

Was this in the vanilla campaign? It might be a bug that stopped the injectors from generating.

Yes, it was a skeletton in the vanilla campaign.

This sounds like it was an addon error. Skeletons definitely start with injectors and a steam generator.
