post over at SHSDuring three installations with WeiDU v230, it would always delete some files exactly at the same point (after infinity-animations's component 0).
File types are are, tis, wed, bmp (lightmaps) and dlg.
After switching back to WeiDU v227 the installation worked flawlessly for that component, and there were no further (obvious) errors after switching to WeiDU v230 for the remainder of the installation.
