help with Flame Knives

[wingyuu]

I thought I'd start a new thread since it's starting to look like I may have more trouble in the future (so far, I've only needed help twice, including this time).

Map 7 - Graaka can shapeshift between 3 forms. I killed both cerebrates, freed all 6 probes, and have them all carrying the 6 pickup items that are on an isolated island. In the area located adjacent to the north tower, you witness a 3-way battle between Protoss, Zerg, and Terrans. There's also a neutral Protoss base there and any surviving Protoss warriors are neutral. Only one teleporter and two custom buildings (one in the base and another on a raised platform that I can't get to) in that area. Been looking around the map for anything to do with the 6 items, but nothing shows up as a multiple of 6. Brought Graaka to all Nydus Canals; only have 2 sets of usable ones. All teleporters are unlocked.

No idea what to do. Any help is GREATLY appreciated.

I figured it out and I'll post it here in case someone else gets lost. Each of those "crystals" (the picked up items carried by each probe) must be brought to a corresponding landmark. Each landmark is distinct in that it is a brick/paved ground with a nonselectable structure on it. Each landmark has corresponding marks to the 3 pairs of items. Each brought item, in which the probe and the crystal disappear, vanishes/destroys a mineral field standing between you and the north tower. Once all 6 are used, Grakaa can freely go to the North Tower.

Map 11c - can't get Khemal past the 3rd trigger mechanism. (I can see how to solve the entire map once I get khemal past this crystal barrier.)
Map description - kardin, khemal, and graaka each take separate paths thru nayadar to escape the maze
Any help is greatly appreciated.

Advance all the other characters, looking for trigger mechanisms that look the same. Some may be hard to spot, but from memory, at least one of them requires more than 1 character at a triggering location.

Figured out the problem - some switches/triggers only work when the character comes to the trigger from a specific direction. Had to reposition characters a few times to get certain triggers to go off. FYI for anyone who may have this trouble in the future.

Oddly, this isn't the first time I've encountered this problem in a map.
