Would be good to resolve this for the 2.9.0 release.

Priority: highnormal

Unfortunately we have to remove this ticket from the 2.9.0 roadmap; some of the modded scripts they are using apparently have some oversights which bring the SCUMM machine stack pointer to negative values, i.e. out of bounds memory access. This sits well on the original exe because they don't have a strict memory bounds control like we do, but in our case this crashes the engine.

I made sure to send the relevant information to MegaCat, so that we can sort this out in the future.
