Since the 1.1 update, every time when I am closing a window there is a text output.
Looks like some debug helper, for example:
{entity = {__self = "userdata"}, gui__type = 1, name 85, player_index = 1, tick 19585289}
{gui_type = 3, name = 85, player_index = 1, tick = 19585062}

I am pretty sure is this caused by this mod, as if goes away when disabling the BRL and comes back when I activate this mod.

Line 299 .. the game.print should be commented out

local function on_gui_closed(event)
  game.print(serpent.line(event))

Thanks! Should be fixed now.

was about to try figure out what mod caused it.
