Remember ID and Global Name for future Iterations

[Ewanderer]

ince if mod load order changes etc a save might be left broken

so that register sprite is called with global name i already recognize, i give it the previously assigned id. and the start counter is based on that internal lookup table lenght

[Ewanderer]

use offset rather than raw value, so that if we need to raise start value, we don't lose data?
nvm just raise limit
