Display Bug: Ritual Tablet that is supposed to decrease reroll cost increases by 1000s%

I can't imagine this is desired. I'm assuming it's a result of the fix to the infinite reroll glitch in the beginning that got people banned.

I just added a ritual table to one of my towers. One of its explicits was supposed to decrease the reroll cost. Instead it caused it to increase -- ridiculously.

It almost seems like a weirdly clamped overflow. Though for the life of me I don't know of any numeric types that have min / max at 2*13 (8192). But it would make sense, as 8192 - 8177 is 15 which I believe is a reasonable reroll reduction explicit value.

You can see below:

Now all my influenced maps have "rerolling favours at ritual altars in area costs 8177% INCREASED TRIBUTE"

Edit:
Thankfully, it appears the tablet is behaving accurately; my display of map mods in the map shows that rerolls of rituals are decreased by 16%, and the costs to reroll is 840 instead of 1000.

It's visual bug. Everything is fine.

encountered this too. had to avoid the whole tower section just to be safe. not gonna risk it not able to defer the 4d omen
