Excellent news, thanks!
Each time I change the Scorpion Engine version, it may add those little glitches that you described. I have a text file list here on my computer with many, which are accumulating. Not actually the engine's fault, that's the nature of game development in general, it's hard and unpredictable. Even more on retro hardware. Also, that's why the majority of Amiga ambitious game projects may never be finished: the motivation wears off as the problems tend only to accumulate towards the project's end!
But, on a lighter note, after this good news, I can see the light at the end of the tunnel. Crashing like that on world 5 was a serious issue that would harm severely the project, while minor issues here and there are to be kind of expected due to the experimental nature (as an ongoing project) of the Scorpion Engine.
