Small modmod - No infinite units

[raxo2222]

This is exactly what Force Obsolete was designed for.

I can't remember if you can link it by unit or not. If you can that would be better than using a tech since units can move between techs and it would be something else to remember to change.

Yeah, there is other forceobeolete tag - its used for Neanderthal units to replace normal units.
