The dinos stats that are higher than 127 are going back to -128. Happen on servers with a max wild level of 400-500 or more. I already fixed that issue on my fork https://github.com/flagoss/ArkSavegameToolkitNet/commit/17cff5654e8e228af2e5c4ee381f36c571115671 Its only changing some variables type from sbyte to byte.
