Script Counters Roll Over to Max Int When Going Below Zero

[SUCCESSOR]

(Emphasis, mine.)
...then it can cause rollover. It's illogical for a counter to roll over anyway. That's my real point. That, and the behaviour doesn't match internal counter ref behaviour from items, IIRC.

Rpgs have this problem. A base value is always expected to be in range 0:N, but modifiers are valid if < 0 or > N. Finally, final derived values are again expected to be within range of 0 to N when the dust settles. (This is not the case with statistical values but ZC doesn't have those. ) I would assume that setting a counter (with implicit positive range) to -1 would set it to 0 and not 65535.

What are all the counters affected by this?

I would expect setting the counter directly through script for it to behave like the variable it is. I would expect that letting the game handle adjusting the counter to behave as it should.

That's what we have drain counters, right?
