On specific wikis, (the only 2 i've seen are the Slay the Spire wiki and the Don't Starve wiki) the discord integrator crashes the entire mobile browser upon loading. It does not occur on every wiki that has the discord integrator (like this one), only some. The only way I've figured out how to avoid this is by manually forcing the page to stop loading about halfway through, but that can result in images from the articles being missing, or the entire page being blank if you press it too early. If you press it too late, then your browser crashes.
If these wikis have a large amount of users online at a time there's nothing much that can be done other than switching to a different Discord integration script. DiscordIntegrator only embeds the widget Discord provided, and if Discord provides too much content mobile browsers don't seem to handle it very well.
