We have released a small update for Isonzo today, with the following fixed and improvements:

• Improvements to Marmolada lighting
• Improved Marmolada performance
• Various gameplay and visual improvements for Marmolada
• Vetterli Mod. 1870 is no longer limited to 1 per team
• Fixed ammo clip scale and reload animation for M.14
• Fixed players getting stuck in grenade throw animation state
• Fixed Linux and Mac crashes since last update

This patch increases the network version, meaning that you should update the game before playing online again.
