My small group has been spamming AC lately trying to get a few Bodb’s Pigaches although the past 4 drops have all been ares feet and skadi legs lol. None the less we have tried repeatedly in different spots to recreate this and I even asked Kaeko in-game for some clarification but have had no luck "disabling" MR. At first we tried sticking AC between two pillars since his sides extend and we figured that could be the glitch but nope. After getting more information from Kaeko and him stressing your tanks back has to be as close to the wall as possible or jammed in a corner we tried a few more placements. So far we have not been able to reproduce the no MR'ing. I know it's hard to explain where we've tried without SS"s but I'll do my best:
1. Between the inactive teleporter pillar + wall in AC's main room (SW area, back obviously not against a wall)
2. Between a pillar and the corner where the room turns into the small hallway before the first door (back not against a wall, AC sort of diagonal)
3. Between 2 pillars in the small hallway before the door with tanks back to the wall.
4. Utmost NW corner of the room jamming the tank in the corner. I had my hopes up for this one since the front of AC seemed to be jammed in a pillar.
5. Same NW corner but instead of jamming the tank into the corner diagonally, he positioned himself with his back to the N wall but stayed in the corner.
If anyone is able to find a position where MR is "disabled" a SS would be great. We'll keep trying and hopefully stumble onto the right spot.
