Cover calculation is extremely slow for large tokens with many small tokens on top

[Zamrod]

If you create large vehicles and put a bunch of people on them and then have weapons on the vehicles then when you set MIDI QoL's optional setting for determining if Walls Block attacks to dnd5e helpers + AC and dnd5e helpers is set to 4 points as its method then the attack roll will take about 30-45 seconds to resolve and lock up Foundry. If you change Midi QoL to just "center check" it resolves immediately.

If Helpers is set to centerpoint only check (assuming the midi option "center check" you mentioned is a different thing), do you also get a similar speed up?

Just trying to triage -- this issue doesnt surprise me, but I havent seen it myself. I'll look into it when updating for v10. I can't promise anything, as the core logic is a nested loop, but maybe we can find some easy wins.

It speeds up quite a bit when I do that. It still locks up for about a second though
