Hmm, and I still have no solution. FOr some odd reason when a city is built near the edge of teh map PB will have issues since the tiles it is looking for to get info off of are outside the map region. Not sure how to fix this yet but I will keep looking into it. As for problems with "H" not wanting to work with unexplored areas is new to me. Unless I am misreading you and you mean outside the visible map as in outsdie the playable area of the map (I.E. the north south borders) I will defintely look into the highway code again though.
As for barbarian settlers, I have yet to experience this on this scale that you meantion. I do know the following; 1) if you load one of the 7 Conquest scenarios you will get tons of barbarian settler on that screen. 2) If you kill a unit this erases the memory of that unit, however I have noticed on occasions that Civ 3 leaves a 'trace' of that unit in memory. That is it leaves the point to the section of memory that that unit used to be at, however, there is no longer unit if at that location and thus PowerBar reads that as a barbarian settler (It does this in order not to crash, else it would crash and one of teh pervious coders made PB list unknown units as barbarian settlers. A little bit more on this, each unit has a code associated to it and PowerBar extracts all this info as well as teh unit name etc with that number.. very complex, all takes place when you press LOAD). Thus I believe the "Barbarian settler" is in part a Civ 3 bug with leaving points to 'dead' units. (granted I might be able to work around this with a different name but you get the point)
"Unable to apply selected filter" I haven't gotten this yet not sure what sets it off entirely. I do know that if you start anew game and load powerbar without running atleast one turn, you will get this error. Sometimes you will get this error if you load a saved game and then load powerbar without running any turns. I also know you can just get them whenever. The whenever ones I attribute to PowerBar being a memory trainer and Civ 3 having memory leaks such as the points to 'dead' units. There is a chance, and a saved game would help, but I think a bug or memory leak in Civ 3 is the problem here. Then again, it is happening so much that it could just be a PowerBar glicth. I can't tell for sure as I only get this error if I don't let PowerBar run atleast one turn. If I do that I never get it!
I know this doesn't help alot, but should give some guidance and perhaps can help you help me by looking for these condtions and report results to me. Here's what I need:
1) a saved game of when the error, barbarian settler, etc happens.
2) what you were doing when it happen (I.E. I'm looking for a trigger, did you just do a whole bunch of things with PowerBar in a short period, what buttons did you press previous if you can remember.)
3) game version and patch to include Gold edition (as Gold edition and teh other new 3 set combo may have different offset which could be the cause)
4) a screen shot (press the Print Screen key and then after you close Civ 3 open paint and paste it there, save it and e-mail it to me)
5) all the above in an e-mail. I may not respond right away but I will take teh info and when I have time I will research it and make a report to you and on here.
Thanks!!
