Real-Time Game Tweaker

[I like Serena]

Hmm but isnt there already code to do that when the world is generated?

Yes, but it's in a different executable (magic.exe).
Not really easy to incorporate.

Generating completely new random lairs is a bit of work.
Exactly as Jtm already pointed out.

Edit : At random times MOM tweaker refuses to recognise that dosbox is running when i click connect...only way to solve it seems to be to restart dosbox.

I have seen this happening as well, and I have checked it out.
It turns out that the signature has been destroyed due to an access violation.
This would mean that your MOM might not be entirely stable any more, so it's a good idea to restart it.
Presumably this should be less common with the Insecticide patch.

Note that it's enough to quit the game and immediately continue it.

When the connection has been established, the signature is not used any more, so the connection will remain.
