I have a major bug after leaving underdark with those 3 new territories that are forests. whenever I try to enter any of them - the game either crashes or freezes while loading that territory

I have installed BGT 1.05b with the patch of 15 january 2008 (or what was the date)
BP 1.77
and Worldmap 6.6.1

nothing else.
as you understand - starting a new game is not an option now

I also cannot use my savegames in a clean BG2 as whenever I try to open the global map there the game crashes because of previously converted saves by bp-worldmap.

is there any way to fix this bug because I can't continue the game
or at least bypass it somehow (don't know... cheating the Lanthorn into the inventory maybe? or any other way... also I don't remember but are those forests are of a critical importance to the game or can I ignore them and still get to Irenicus?)

and another question - as I remember I can import savegames into ToB - so if I will import them now - will all states with companions (like friendship/romances) be transfered too (I've noticed that you can probably convert savegames to not include information from worldmap into tob part of the saves so I can play a clean ToB)?

cheers.

p.s. I also noticed that two of those forests were available before the time when they should appear on the map (worldmap 6.6.1 bug?), but I haven't visited them just to avoid any bugs.

attention SPOILERS!

I'm using bgt with bgt-big picture and worldmap 6.6.1
but I'm very tired of all those bugs because of this and the final bug that made me install clean bg2 was that no meeting with Irenicus in spellhold was triggered - and in the rare cases it triggered he didn't seem to notice yoshimo in my party (I see you don't have Yoshimo with you etc) even if he was there. and also that led to another trigger with sleep gas in spellhold not working. (it was the bug among all other bgt bugs which were less annoying)

so I've made a clean install and savegames seem to be loading well (and all those triggers worked from the first try though Irenicus still didn't notice Yoshimo, however Yoshimo appeared in the next sequence as a traitor which was normal)
however as soon as I open bg2 map the game crashes - as far as I know when installing worldmap converts savegames adding to them/changing something. probably the game crashes because of this?

so I would like to know - is there anyway to convert savegames back to normal? because I really wish to avoid restarting the game (already 2 weeks in it).

thanks in advance.
