[LDCad] parts update making MLCad behave odd

[Harald Christ]

Hi Team!

Just updated my MLCad v3.51 with a few of the latest parts updates (from Parts Update 2025-02 onwards)

I did it the way i normally do:
download zip file
extract to folder
copy parts, s, textures, p, 48, 8 to their relevant folders
run mklist
scan parts in MLCad

This has always served me well in the past.
However this time, there are lots of vacant spots in the part selection menu on the left.
Worse still, every file i load (ldr or mpd) fails to show some of the builds.

I know they are there, because i can make partslists from the file, but i can't view, or select them.
If i select all, then delete, then UNDO, the image shows. But saving this over the old file changes nothing.

Also, if i start a new file by dragging visible parts into the editing windows then all is good, but as soon as i drag one of the NON-visible parts, and refresh view, all the parts disappear.
Same as above, they are still "there" when making a partslist, but i can no longer view or select anything.

I've found this also seems to happen if i download a complete copy of ALL of the parts.

Is it something i'm doing wrong, or am i doomed to using old parts forever?

Thanks in advance.
