setVectorLines on object sometimes disappear#807

Vector lines drawn on an object (vs global) sometimes disappear mid game. If an object redraws them (say, during turn change) they usually come back sooner or later.

The Twilight Imperium IV mod has several tools that draw lines on an object (to make it easy to erase and/or redraw that collection of lines without interfering with other object or global lines). This generally works great, but they disappear on occasion.

There are several scripts that draw lines this way, including one that just draws a rectangle on an object, so I’m less inclined to believe this is a script error.

Unfortunately I don’t have a better idea of when/why it happens, nor does it happen often.
