It took awhile, but I decided that since this path you gave me includes "Roaming" you must be talking about a registry setting. My game install directory has no path anything like that. My registry (win 7), doesn't have anything like that. I have a file damaglog.xc under J:\Games\World_of_Tanks\res_mods\configs\xvm\Aslain, and I tried renaming that to make it re-create, that had no effect. I also tried editing some x/y values I found in the file itself for damage log, and that had no effect as well.
I went back to thinking about editing the file and was looking at this:
"lastHit": {
"$ref": { "path":"damageLog.log" },
"x": -120,
"y": 200,
I thought "hmm, x index is negative, what if I flip that flag to postive? BINGO, back where it should be, well, visible anyway.
