Medivac boost isn't a buff

[WickedFridge]

When trying to check if Medivac could use their boost, I tried checking if the medivac was actually boosted, checking its buffs. I've found the Medivacspeedboost buff in the list, but when a medivac is boosted, it doesn't have any buffs.
my code reads as follow but doesn't work (as medivac.buffs is always empty) :

if (not medivac.has_buff(BuffId.MEDIVACSPEEDBOOST)):
    medivac(AbilityId.EFFECT_MEDIVACIGNITEAFTERBURNERS)

The Unit object don't update themselves. My guess is that you don't refresh the Unit object via

medivac = self.units(UnitTypeId.MEDIVAC)[0]

You can verify this by checking if medivac.position is the same - then you are using an outdated Unit object.
The unit.tag is unique so you can find the medivac in the next frame/iteration (assuming it was not destroyed) via

python-sc2/sc2/units.py

Lines 506 to 518 in aa247cc

	def tags_in(self, other: Iterable[int]) -> Units:
	"""Filters all units that have their tags in the 'other' set/list/dict
	Example::
	my_inject_queens = self.units.tags_in(self.queen_tags_assigned_to_do_injects)
	# Do not use the following as it is slower because it first loops over all units to filter out if they are queens and loops over those again to check if their tags are in the list/set
	my_inject_queens_slow = self.units(QUEEN).tags_in(self.queen_tags_assigned_to_do_injects)
	:param other:
	"""
	return self.filter(lambda unit: unit.tag in other)

Actually the medivac I use is different in each iteration, so I don't have an explanation as to why that is
