Finally getting around to this. Would you be so kind as to re-base it to 0.96.8 rather than master?

Stringtable entries don't work in my testing as well, but re-base is more important.

Will do, though it might take a bit as I'll have to get back into coding SQF and I haven't done that in a good few months. Should I make a new PR when that's done for the 0.96.8 branch?
I'll have a look at why the stringtable entries aren't working too, thanks for pointing that out!

The stringtable is okay. The problem is in the mission_params.hpp, you added +2 values in each param (Example: values, goes from 0 to 33; texts, from 0 to 31). So the game takes the values instead of the stringtable. Fixing the mission_params.hpp resolves this issue.
