System Information
Operating system: Windows 7
Graphics card: NVIDIA GeForce GTX 1050Ti

Blender Version
Broken: 2.82a

Short description of error
Segments are messed up when any nearby Vertex with a smaller Vertex Id is deleted.

Exact steps for others to reproduce the error
Click "Mesh Debug" -> red numbers are now visible, I assume theese are the Vertex Ids.
Select any 2 Vertices with Vertex Ids greater than 0.
Click "Segment" -> a new MeasureIt Segment is created.
Select any nearby Vertex with a smaller Vertex Id, then press "DEL", then choose "Verticies" -> the selected Vertex is deleted and all the MeasureIt Segments are recalculated and messed up.measureIT_bug.gif

This is a know limitation. The meassure is done between vertex using the index of those vertex, so if you remove the vertex, the meassure changes.
