Client crash when zoning from Durotar to Tirisfal Glades on a zeppelin

can you try clearing your cache and trying again, unable to reproduce

Sorry, I don't have the server running anymore. Took you a little under 5 months to reply, so I gave up.

This affected an older version of the server, I believe R18 or R19. I have not seen it in R20 or R21.

Yes, I fixed this on Zero a couple years ago or so on Rel19

This bug is back (?) with v21 of mangos one
just did a clean v21 database from github install, with the v21 server files from here, and vmaps etc from the v21 extractors
the cache folder is deleted but the client hangs/chrashes when the airships or alliance boats should load the destination zone :(
"ERROR #132 (0x85100084) Fatal Exception
Program: D:\Games\Wow\World of Warcraft 2.4.3\Wow.exe
Exception: 0xC0000005 (ACCESS_VIOLATION) at 0023:0060DB5F

The instruction at "0x0060DB5F" referenced memory at "0x00000120".
The memory could not be "read"."

Client is 2.4.3 (8606)
tried on several accounts, and on three computers with same result.

downgrading to my v18 database and serverfiles and transports work's fine.
