I did some poking around on google on this little problem but it seems theres no prior documentation - I had to try here...
*possible spoilers - beware*
I got Baldurdash installed via BWP, and found the special rogue stone after the guarded compound encounter. But the twisted rune entrance at bridge district does not recognise the fact that I have a rogue stone on me, and every time I click on the entrance, the following message shows up - which is whats to be expected if one has NO rogue stone: "you peer through the door ... ... if you stepped through"
Of-course, I tried having both the special rogue stone AND normal rogue stones on me, but the game still fails to detect.
I am guessing this must be some bug. Any workarounds out there? And by the way, whats the area code for twisted runes? Just in case I had to CLUA my way there if no other choice. Thanks guys.
PS:
Another possible bug report: The male wizard (along with a female fighter?) that greeted you in the guarded compound - if the party responds aggresively to them, they will tell you to meet them upstairs and dimension-door away. However, I found that if this was done in my game - the male wizard fails to teleport away, remains neutral at the spot, and when my party advances further through ground floor, he turns hostile, and is UNKILLABLE.
I got through this problem by selecting the "we will get out of here ASAP" option, then again blatantly walk past them - only then, did they teleport away together properly.
