Character Stuck When Leaving NPC Vehicle

[Manaspark 0]

• Type of Bug:
Phase Forged NPC

• Description:
When leaving an NPC vehicle forged after the server's update to 8.3, the player is unable to jump or fall.
Changing maps or phases does not resolve this issue, which persists until relogging. 
You are still able to walk up slopes and fly when toggled on.

The first gif shows the result of dismounting a vehicle NPC (646737) which was forged while the server was still on 7.3.5. This appears to be the intended behaviour. 
The second gif shows the same action being taken on a vehicle NPC (701852) forged after the first 8.3 update.

NPC 31157, a default blizzard NPC, doesn't exhibit the bug, however NPC 1209335 does. Both use the same displayid - 26303.

• Steps to reproduce:
Forge an NPC with a valid vehicle ID and enable it with .ph f n vehicle. Click on the vehicle to enter it and click to dismount.

• Expected result:
The player should be able to fall or jump, as with blizzard (e.g. 31157) or pre-8.3 forged (e.g. 646737) NPCs.

• Observed result:
As shown in the gif above, the player is stuck and unable to jump or fall until relogging.

• Reproduction rate:
As far as I am aware, this only occurs on every NPC vehicle controllable by the player. 
NPC 1209347 (displayid 30874) is an example of a vehicle which the player cannot control, which does not exhibit the bug.
