Thanks Cyborg, all this is because my game has crashed in the middle of a fight, I was experimenting with the stock game + some essential mods for it. Even patched and modded with the essentials, the stock game remains very unstable, but I had to know for my investigation
I have taken the risk to delete these files prior of re-activating my TWoS in JSGME, the game worked fine afterwards without problems. (I switched to a backed up career and a backed up SH5 folder for the savegames of course). Problem solved.
Cheers,
