Strange, I have the same version of Dosbox running the game. Yet your table's pointers pointed to the wrong addresses. The base pointer is correct though.
Does it work diffrently on each PC somehow? Anyway I updated the table (that guide is helpful) to work for me. Might as well include it here too:
Guess what: It's the language setting.
GoG installed the game in my prefered language (German) and if I switch to english, the addresses of my table are wrong.
Your table does not work, either... let me guess, you habe installed a third languge?
I'll update my first post with a table for the english version.
The problem is most likely having to do with cloud saves. Enabled or disabled, the cloud saves completely changes everything in the older Dos games. This is evident in the way none of the older savegame editors work if cloud saves are enabled.
