SentryTurret unknown startDirection variable

[L]

ERROR in
action number 1
of End Step Event
for object SentryTurret:

Error in code at line 72:

    if image_xscale != startDirection {
                          ^
at position 25: Unknown variable startDirection

Don't know what caused it, I believe it was a one time thing but not sure.

Amazingly, it seems this is still relevant, since basically the same bug has been reported for 2.4.1:
___________________________________________
ERROR in
action number 1
of Begin Step Event
for object Sentry:

Error in code at line 19:
       currentWeapon.startDirection=startDirection;
                                    ^
at position 35: Unknown variable startDirection

Analysis: It looks like a desync between client and server during play, where the server associates a sentry object with a player while the client does not. The sync code (Player, User Event 13) creates a new sentry object in that case, but does not set its startDirection variable. When this happens during normal join the full update sets all relevant variables, but in a quick update the resulting object is not complete and will lead to this error.

Checking a bit further, while sentry creation seems to be fully synchronized, sentry destruction is not in all cases. (e.g. when a sentry gets too close to another). This is probably the source of this problem.

Improved the sync of autogun destruction, which should fix this problem.
