Thank you for the save and determining it was "Innocent Allure" perk. It's not really the perk itself that's the issue but the effect it applies in combat that causes the crash. When using a tease, if the opponent is hit by the lust damage, the perk will apply a "Lust Staggered" effect, which also applies the normal "Staggered" effect. Since both exist at the same time, the combat status effect handler was removing both at the same time when it saw that one had "expired", causing the next check to run into an unknown property when checking the other status and inevitably crashing.
Unless I'm misremembering, I thought this was addressed way back in the Flash version of the game, but it may not have carried over to the Javascript rework. But in any case, I've reviewed and edited how the effect applies. It will apply the normal "Staggered" effect, as intended, it'll just have a slight flavor adjustment for being the lust variant of the effect.
Hopefully this will fix the issue for the next release.
