			It's unclear whether attack-mode AI state is fully saved or not. I had some severe non-reproducibility issues in recent testing.

			Floaters have problems with stairs under Seb76's loader as well. Furthermore, in the debugging modes, it is not possible to start going down stairs the way a flying-suit X-COM unit does (select the stair rather than the square in empty space)

			I'm not sure whether this is specific to XCOMUTIL or not. Floaters have problems with stairs. I haven't gotten around to testing this with Ethereals.

			Floaters can go up stairs fine (verified in a recent game), but I'm having problems catching them in the act of going down stairs. They are often found at the RMP node at the top of the stairs, facing due West (internal facing 6). From TU usage I think they do spin around, but the facing west and position are a steady state.

The following files are potentially inconsistent between different end-of-turns, when no alien sights an X-COM unit or vice versa:
* [[SMOKREF.DAT]] (when there is smoke)
* [[ROUTES.DAT]]
* [[UNITPOS.DAT]] (cf. comments below)
* [[UNITREF.DAT]] (both XCOM and alien units)

Points of further investigation for patrol mode AI:
* Bit 4 at offset 19 in the ROUTES.DAT records: this influences the AI. In my current test suite, both "different nodes" from my reference save were to nodes that had their offset 19 bit 4 set during the AI turn.

Also, is there a quick way to diagnose what AI mode is applicable (both locally and globally)?

Pedantry: X-COM CE with XComUtil 9.6, used an Interceptor with 6 crew. The power plant explosion killed all but 2 floaters.

The general procedure (in Battlescape):
* Save the game at the end of turn.
* End Turn.
* Save game at the beginning of turn.
* <code>copy *.dat *.bak</code>

Then:
* Reload end-of-turn game.
* End Turn.
* Save game at the beginning of turn...in the same slot.
* <code>fc /B *.dat *.bak > diff1.txt</code>
* repeat, until "enough difference files have been constructed".
