Did monster spawns slow down, or...something? Even with Baenarall, Sjin, and Evil in my formation, half the time I'm unable to beat a boss in an area fast enough to sprint. Normally I have at least a full second to spare, but now I'm nearly a second too late.

Not remotely. That's the first thing I checked. I thought maybe I accidentally turned off an ability, but nope, everyone's speed abilities were bought and active. Then I checked if they were actually being applied in the "Other stats", and, again, everything checked out. Even at +200% spawn speed and instakilling, the boss still wasn't appearing soon enough.

That was in Ghostbeard's Greed, but now I'm running Ready Player Two's free play and not having any issues, even with the same crusaders and the same spawn speed. Maybe it was just slowdown on my end? Which would be weird considering the issue was fresh off a refresh of the page.

In any case, I'm not experiencing it now. I'll post if the issue comes up again.

Aaaand I'm getting the issue again in Mugwarts, so I'll just ask outright. What is the average spawn speed needed to sprint? Because even at 150%, it still isn't consistent. I set my formation up and let the game do it's thing, assuming it'd be sprinting and such, but I come check the game just over an hour later and find I'm only at area 665.

It isn't a network issue. Everything is working fine on my end. No internet loss of speed, minimal CPU/Memory usage, the game is running smoothly, the enemies and bosses just are not spawning quickly enough. At 200% spawn speed (using buff cards), I'm killing the bosses and sprinting with just BARELY enough time - as in, the sprint gauge has already run out by the time the boss is killed, and it still counts as a sprint. That's how close it is. Ever since sprinting was a thing, using these same speed crusaders left me able to sprint with a little less than 1/4th of the gauge still remaining, but now it's a hair's difference between success and failure. When Sjin and Chef have their speed buffs and my spawn speed is at 300%, it's barely enough to kill the boss AS the gauge is on it's last frame of animation.
