SCUMM: Loom (EGA) - Path finding or overlay issue at Dragon's caves

[antoniou79]

This in on Windows 10 x64, with a recent local build from HEAD master of 2.6.0git, testing with LOOM DOS EGA, using the orchestral audio feature.

For this I've applied the patch for the MT-32 upgrade to LOOM and set my Audio settings for the game to use "MT-32 emulator" as Music device. You may also need to do that for the attached save game to work.

How to reproduce:
Upon entering the caves, and casting the spell for Night Vision, walk to the cave entrance to the right and enter it.

What happens:
Sometimes but not always, Bobbin won't be shown to enter into the cave but instead he walks a bit to the left while clearly being outside of it. The game then teleports him to a random cave.

What should happen:
Bobbin should go into the cave and then be teleported to a random cave.

I'm including a save game at the point of entering the cave, and a screenshot showing Bobbin a bit before the game teleports him.
