If spawned as a custom enemy (createentity entry 56), or spawned outside of the rooms they spawn in in the main game, they will repeatedly clone themselves every frame, which profusely leaks memory. In fact it quickly causes a crash in 2.2 and previous, but 2.3 fixes that crash, so it just keeps spawning enemies endlessly, which eventually lags the game, and eventually can out-of-memory your system (bad!). The problem is those movement types rely on entclass::setenemyroom() to change their `behave` to be 11 or 13. Else, the new entity created will still have `behave` 10 or 12, which will create ANOTHER entity in the same way, and so on, and so forth. So to fix this, just make it so if an enemy is still `behave` 10 or 12 by the end, then, just set it to -1. That way it'll stay still and won't cause any harm. I considered setting the `behave` to 11 or 13 respectively, but, that's probably going farther than just fixing a memory leak, and anyways, it's not that much useful for me as a custom level maker, and the entities spawned aren't really controllable.
