New description:

 I was testing Hoyle 5 a bit on my phone, with ScummVM 2026.3.0,
 specifically the checkers game. It worked fine for a bit, but then it
 suddenly crashed to the ScummVM debugger.

 I do not know how to reproduce this, and unfortunately I was only able to
 capture a bit of information before I accidentally closed ScummVM.
 Hopefully it's enough.

 The crash message:

 {{{
 ERROR: [hoyle5 1200/64999 movLst::at @ 04f3]:
 parameter 0: 000:000 (null, integer), should be list
 parameter 1: 000:000 (null, integer), should be null, integer
 [WM] kList(At): signature mismatch!
 }}}

 A partial backtrace:
