wooaah my game is really laggy after the update of this mod. Disabling it fixes the issues, but obviously I can't use this mod if it's disabled.

only with the latest update? strange, might roll it back until I can see what's up

I have a LOT of mods enabled, so it could be a conflict, but it would be a full-time job to figure out which is the cause.

But yeah, it was working fine yesterday and the day before, until the mod updated today.

if you open the console (~) are there error messages? if there are any from the pack it would help to know what file and line number they say

I'll check when I have the time and keep you updated

This is about all I could find in my log: [INFO] - Running Lua Script: C:\Users\ginji/Documents/My Games/Binding of Isaac Afterbirth+ Mods/potatopack1_1846529189/main.lua

there's a lot of errors from 'more mushrooms', does disabling that have any effect?

Huh, would you look at that, it works now :p
idk why your mod is suddenly incompatible with that one. It worked fine until today...

Here's the mod if you're interested in looking into it: https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=1246373744&searchtext=more+mushrooms

ah, there's a problem with it where it doesn't use the actual player count, it just checks for 4 players, so if there's only 1 player its checking for and not finding a player 3 times every frame, which causes issues later on when it tries to adjust player stats or check their items

tried running the game with the mod and noticed slowdown, fixed that issue and played and it seemed fine, told the mod makers about it but since they haven't done anything since 2018 I doubt it will get updated

if you don't mind editing lua could you check if it makes a difference?
basically just go into the mods statAPI file and replace all the instances of
'for i = 0,3 do'
with
'for i = 0, Game():GetNumPlayers() do'

The fix you suggested didn't seem to work, it's still plenty laggy. It's fine though, I value your mod much more than a silly mushroom mod.
Thanks for the help and the invested interest, you're a good modder <3
Good luck with your mods in the future.

2 bugs I've found so far:

1. Happy shroom causes severe lag upon pick up (for seemingly no reason).

2. Cursed mirror causes a transparent, passive and invincible Isaac to appear and slowly move around the room, preventing the room's doors from opening as if it were an enemy. (Got this one during a good greed run, rip)

still trying ot work out what would cause the happy shroom to lag as I don't notice anything on my end, the transparent isaac is intentional but should not be locking the rooms, will look into that

For me, the mirror Isaac would make cleared rooms locked for a split second, but would immediately unlock afterwards.
