Bugged mining leves, St. Coinach's Find

The mining leves Hybrid Hypothesis & Crystal Mess at St. Coinach's Find are currently uncompletable due to a bug.

Both have a node near the top of the ramp down from the camp to the giant area (near where one of the FATEs has a 'initiate' mob when it's up). This node is currently bugged & does NOT display - thus making it impossible to complete either of these leves. I've done both multiple times (been grinding up to 50 mining on these), & as of this morning (8am PDT), this bug is present & blocking completion of these leves.

(P.S. It would be really great to get back the 3 leve allowances I wasted discovering (1 on each) & then verifying (1 more) this bug.)
