SCI: PQ2: Crash "[VM] Trying to instantiate class 6 by ..." on room change

[ahnurmi]

I have a save game (attached) that's stuck. If I load it and walk up north, the ScummVM debug console pops up with the message:

ERROR: [VM]: Trying to instantiate class 6 by instantiating script 0x3e7 (999) failed!

I got the same message two times earlier in different locations: first time when trying to exit the plane, second time when trying to enter the park. But whenever I loaded a previous save game and tried to reproduce, the game managed to continue. But not this time, this time it always reproduces and the game is stuck.

The game was played and saved using ScummVM 2.6.1 on MacOS 12.2 (Apple M1).

PQ2 (DOS / English) resource file hashes are:
