This TQVault adoption consists of two main feature blocks: Xtra Large Increase vault space und add support for enlarged caravan/transfer areas.
It supports Anniversary Edition as well as classic Titan Quest and brings new features like extra space.
TQVault XL is a new TQVault based on TQVault 2.3.1.4. I had trouble with 2.3.1.4 back in 2014, and when I switched to 2.3.0.4 my problems ended.
