Describe the problem

I have gotten a 'ForbiddenError: Invalid CSRF token. Please refresh the page and try again.' error at least once a day since the latest update to the release branch. I only have SillyTavern open in a single tab in Firefox; it is not open in any other browser, nor is it open in a second tab.
It seems to happen after SillyTavern has been open for several hours, though I don't have an exact timeframe for when it occurs (late evening, my time?). The issue did not occur before the latest update to the release branch, and I have not changed anything about my setup (extensions, et cetera) since that update.

There is no indication that there has been a problem with the CSRF token until I attempt to send a message in SillyTavern; SillyTavern eats that message, loses it entirely, and immediately outputs 'ForbiddenError: Invalid CSRF token. Please refresh the page and try again.' to console whilst appearing to be generating a message in the frontend (ultimately doing nothing). SillyTavern's UI does not pop up an error itself that I've seen, and does not show any sign that it's non-functional at this point.
Because the issue is only evident on trying to send a message or interact with ST, it's kind of hard to pinpoint exactly when whatever is happening... happens. I tend to open ST early in the day and use it sporadically through the day, and haven't seen the issue earlier than the evening.
