Need help: no waystones are dropping in T7 maps. Potential bricked Atlas??

Hi guys,

Could use some real help here. I've no clue what's going on but I expect my atlas to be bugged. I just don't know how to prove it (yet).

Started mapping and waystone progress went smooth untill I hit a wall at T6. Every map dropped anywhere between 1 to 3 waystones.
T6 maps weren't dropping T7 waystones but Doryani sold them. I bought his stock since I had to do a corrupted nexus at t7+. After having completed the nexus I proceeded to run T7s.

5+ maps later and no other t7 or t8 waystones were dropping. All my atlas points went to more waystones and The High Road node for a tier higher.
Since I had no more left, I upgraded all my waystones to T8 thinking I'd start getting drops again. Sadly no. I've now run at least 30+ t7+ maps but ZERO waystone drops.

With patch 0.2.0g out, I assumed the loot buffs would solve the issue. I was mistaken. After levelling up, I bough all of Doriyani's stock, upgraded to T9 and cleared a nexus. I have 2 T7 waystones left.

Pre patch and post patch 0.2.0g, whenever I fall back to a t5 map, I get at least 2-3 other t5 maps in return and usually a t6 as well. I can sustain maps easily up to T6 but once I run a T7, all waystone drops effectively stop.

I have to clear to t12+ nexus now as next objective but there is simply no way for me to climb higher. Character is level 83 and clear out everything easily. I'm properly geared at this point.

The other downside of this: I get no skill gems above level 17 or trial keys for a 4th ascendancy.

Is my atlas bricked? Is this a bug? What the hell is going on?
If this isn't resolved, I've got to stop playing. No sense in just running T5-T6 ad nauseum without progression.

Has anyone experienced this? What did you do to "unbrick" your waystone drops?

Update: last 2 T7 maps did NOT drop a waystone.
Dropped to T5: boom, waystones

Bought a T14 waystone from another player from trade.
Recieved 4 T41 waystones in that map and 1 T15.

Something fishy is going on with waystone drops that make zero sense and appears to have affected T7-T9 waystones for me. Other tiers drop waystones like crazy.
