4 years, 9 months, and 4 days

That's how long the Strange Barrel Bug with invulnerable Spiders has existed. Are you really telling me you haven't been able to fix this bug for THAT long GGG?

If the revive monsters mod from Strongboxes causes issues like that (and don't even get me started on the massive fps drops after you reopened the same box with this shitty ass mod for the 219387th time) then just get rid of it for God's sake. It's a stupid mod anyway that makes your map laggy and unreasonably rippy without providing any reward in exchange.
