Attempt to compare nil with number

[Reign]

Any idea what this could refer to? It's related to the underwater API made by Prado. This API works fine in beta 3, but in PAL it gives this error:



The line 342 in ffi_player.lua looks like this:



And the api is here:

The error is in line 11 of leveltimer.lua in your episode's 31 folder.

I thought so, but that line merely defines a new variable:

local secondsleft = 300; --The amount of seconds left.

Odd.
The error is a few lines down. When it calls Player() have it call Player(1) instead, or just replace those 2 lines with:
local player1 = player;
local player2 = player2;
Works the same.
Regardless, leveltimer is deprecated, so there might be more issues in the future. I suggest using timer.lua
local timer = require("timer")
timer.activate(number of seconds)
for the most simple use. More info on the handbook:

Correct. After fixing that one there were two more. But it's all good for now. Appreciate the quick help a lot!
