Upon opening Vassal, the modules I previously had loaded were not there.
I then tried to load a module and got the error appearing in the error log:
Model: ASUS F102B
OS: Windows 10 Home
CPU: AMD A4-1200 APU with Radeon™ HD Graphics 1.00 GHz
Memory: 4.00GB (3.44 GB usable)
Video: AMD Radeon HD 8180
VASSAL: 3.2.17
Java: 1.8.0_211-b11
Module: Paths of Glory
The error occurs when loading the PoG module, so the corrupt file will be the settings file for PoG, not V_Global. Look in the Preferences directory where V_Global is for the PoG settings file.
