Monster Name: Achuka
Steps:
1. Engaged in Achuka wildkeeper rieve
2. fought it down, using my automaton to tank it while my trusts and i fought.
3. after the first evaluation of about 3200 limit points and bayld, continued receiving reive momentum bonuses, but no further evaluations despite fighting for almost an hour.
4. defeated Achuka, received about 2300 limit points and bayld for winning and items.
5. checked currencies 2 tab, and confirmed the only bayld i received from the WRK was from the first evaluation and the clear.

Note that before achuka, i had fought Tchakka first, and had received 47000~ bayld and limit points from that entire battle. fighting Kumhau afterword, i was receiving evaluations like normal as well, gaining roughly 20k bayld before being put on ice permanently. (nerf lions!) it appeared to be a problem with achuka in particular, but because it takes a long time for them to repop, i haven't managed to test again to reproduce the bug. I was also the only person participating in all 3 rieves.
