Destructive Play Silo Strategy bugged

Since the 3.26.0c patch the silo destructive strategy where you only kill the extra bosses spawned by maven to loot influenced maps seems to be bugged. After 20 maps of repeating silo I only dropped one influenced map, when I went into a shaper guardian map I instantly dropped 2 influenced maps again.
I think this has something to do with the fix you implemented:

"Repeating the same map in a Memory Thread now penalises Item Quantity more, and cannot have Eldritch Influence."

I know it is not mentioned for maven, but I guess it has the same mechanic of witnessing behind it and maybe something went wrong there? Sorry for the guessing I am a software developer myself so I couldn't resist thinking about it.


Edit:
I tested it again and had map drops, dont know if I got giga unlucky.
