Flying drone is fixed on ShieldBattery already (Our flying SCV fix fixed both)

I guess this is a different glitch than the old one. That glitch you didnt need to click a mineral as queue, oh and you couldnt control the drone either but it went to where you shift-clicked.

It is the same basic underlying cause, the mineral thing is unrelated/unnecessary. The sequence of events between this and the SCV one is the same:

1) Make unit do something that results in the game removing it's collision detection (building a terran building, building on a geyser, etc.)
2) Fill the unit's order buffer
3) Cancel the first action

The game then tries to restore the unit's collision detection (which is *also* an order), but sees that the order buffer is full, so that order cannot be queued. The unit is therefore left in that state forever.

Blizzard's fix for flying SCV's was very targeted at the specific SCV case, so it doesn't fix the general issue. (But yes, the drone timing is much tighter than the SCV one)

btw, is there any other bug/ glitch like this? I think I watched a video on FBH's youtube demonstrate like 10 others glitchs around a year ago

Yes but this is another bug than the 1.09 fly drone. Then you didnt need to fill queue-buffer. Just a single queue and a cancel. Same with Templar merge, but the precision on cancel there was actually a thing, not on the extractor though, you could cancel as soon as it started going over gas, i.e you lost control of the drone.

Oh and as i said you even lost control of the unit until it reached your queue destination, these bugs remain in bugged state while still having control.

Having control of your drone is far superior

Which is why these bugs where you have control and can manipulate the game with it has to be fixed.

All of them revolve around the same buffer overflow problem, so one programmer that also understands the game and the SC codebase could probably come up with 10 other bugs in one week of testing various scenarios in the game.

Out of curiosity do you know how blizz fixed flyingscv without fixing flyingdrone?

As i guess you fixed it at the core mechanics of queue buffer class which is why you say you fixed it for everything while blizzard did not, but im intrigued to know how blizz did it as it must be a hacky fix for scv only?

if ( 
  unit.current_order == SCV_BUILD && 
  new_order == RESET_COLLISION &&
  unit.queued_order_count >= 8
) {
  append_order(unit, RESET_COLLISION);
}
