We have released another hotfix for Trine 4, which contains a fix for the join problems in online games and a couple of other fixes. Read the full changelog below:

• A potential fix for the remaining issues with joining online multiplayer games
• Multiple fixes to game crashes
• A fix for situations where an out-dated fan translation mod caused the game to crash. This fix doesn't make the fan translations work, but now the game shouldn't crash and should make it easier for translators to locate and fix the problems with their language mods.
• A fix for the puzzle in Cornelius's Dream, checkpoint 6 in Classic mode Multiplayer. Now only 1 box should spawn instead of 3.
