many items in base are pointing north when I leave/come back

last nite about 8+ hrs ago we had a crash. dom brought server back up.
after that, all the following problems happened. I leave my base, storage drawer faces are missing. I need to use the concealment key a couple times to get them back.
then I noticed some blocks are being pointed northward. refined storage export bus, pointing north.
seared furnace, it is malformed. block is not lit and if you click on it, crash to desktop. break/replace a block, everything fine.
again. none of this happened before crash, post crash, it all started.

as far as storage drawers, this is not the same issue ppl are aware of. No wrenching or anything fixes face. It literally is hidden. hitting it with concealment key once brings up a square then again, it turns normal again. leave chunk come back, process repeats over again.

note that ALL of these issues, started ALL at the same time.

one thing to add. we had 2-3 crashes after this all started. when server restarts and I'm in my base, the problems don't reappear, making this very certainly some chunk load/unload issue. issue is that this didn't start till after that one crash, then, again, all of it started happening at once.

so I had removed claiming quite a few days ago. Just added it yesterday and noticed this problem (mostly with refined storage blocks) is happening again.

I used rftools to tp to another person's base, came back and both a crafting grid and remote storage block were both now pointing north. I think it's a mod interaction between ftbutils and refined storage.

removed claims, still happens.

another note, it moved my storage drawer (spruce) north facing, as well as changing it into an oak drawer.

I'm really scratching my head trying to figure out exactly what could be causing this and drawing a blank really.

There's one thing but I can't see it being an issue but it's the only thing that seems to separate me from other ppl. At one point I had 4 exu2 chunk loading wards around my base. dom broke them during testing. Not sure how he broke them, either creatively or command line deletion, but possibly that could be something. Other than that, I'm really at a loss.

again, steps to reproduce:
make a refined storage setup: controller, crafting grid, etc.
have them facing some direction other than north
use rftools teleporter to leave your area and goto another area for a few minutes.

come back to your area and the above mentioned things happen pretty much 100% of the time for me.

notice the rows of empty mana pools. All those pools are full. I know mana pools sometimes screw up and not show proper full-ness but this isn't that same case. I've never seen it do that in a pattern like this.

also the 2 mana spreaders should be pointing towards the runic altar, not back at the mana battery.

the oak drawer next to altar is actually a spruce, and is also facing north and not the direction it was placed. when you break the drawer, it's actually a spruce drawer that you get back. Goalie has gotten similar issues, biblio bookshelf pointing wrong way sometime after coming back. Pretty sure I'm not only one on server having this problem. No common thread that I can think of at all.

confirmed: pam's harvestcraft blocks cause the wierd turning of blocks when you leave and come back. Just moved all my stuff away from my botania area, and left/came back and it's magically still where I left it. I guess till we have a update for pam's, this problem will persist. Feel free to close issue if you feel it's appropriate.
