Enemy spawning could still do with some refinement

[Ralzar]

In my case I solved it by saving when an enemy was queued, quitting, turning off my terrain mod, loading, which then placed me outside the city gate (to compensate for changed terrain sampler) and wait a second, which caused the queued enemy to spawn outside with me. Kill it, enter building, save, quit, turn on terrain mod, repeat.

I'll file this under "If the solution is stupid, but works? It's not stupid."
