OMG,
In conjunction with Andi, and Peter I have expended ~20,000 hours over a six year period in developing, testing and using AssetX, PEVTools and TARDIS. Along the way I have built the TARDIS suite of repair scripts to automate most of the work. In the process I have nearly reached Repair Heaven with according to Content Manager some 98% of the 200,000 assets in my TAD , gleaned from DLS and external websites plus the builtins, now repaired or upversioned to work at TB 3.5/3.6 compliance. The remainder are mostly garbage and unsalvageable. I still have a heavy dose of testing to do to ensure they are visible and work in Surveyor, Railyard and Driver. CM doesn't guarantee that. But I can say with a great deal of confidence that nearly all legacy assets are useable in TS12, and if required upversioned to TB 3.5/3.6.
With about 95% of the work complete I had intended to release TARDIS 3.6 shortly after TS12 SP1 release, whenever that might be, and certainly before 1 Sep 12 when the next N3V Trainz Life-Cycle policy milestone is due.
PEV has given me tremendous support both in time and expertise. All this work with so much at stake is now in jeopardy because of the mindless actions of others. I hope Peter can find a solution to his current misfortune, and that the whole Trainz Community including me (over 500,000 strong now with iPAD) can then heave a great sigh of relief.
