AP Mines

AP mines, when built, spawn into 10 minutes, all placed within the same point.

I only found this out after building 49 of them and suddenly not being able to build anything else – after ctrl-Zing them I noticed that I had 490 units selected!

Did you have 10 engineers building mines? if so, they’ll build on top of each other.

There’s no Lua telling them to spawn like that, and I just had a single engineer build a mine, as well as .gave it, and could not replicate this behavior.
