Problem with changing file paths and weighting

[BadHabitz 235]

I'm having a problem editing some models I have access to. The models don't appear to have weighting issues before the models have their file paths edited, but after being edited and changed I get weighting errors.

 

Steps to reproduce the issue

1. Model has errors in .rpt from missing texture due to incorrect file path. 
2. Change file path.
3. Save p3d.
4. The .rpt now has many lines of errors. Example "mod\helmet.p3d:0, vertex: 7393, sum of weights is 200, should be 100".

 

I have no experience in weighting, and I don't touch it when I'm editing the file paths. I need to figure out how to fix this or get around it so these errors don't spam the .rpt.

 

Any ideas? Thanks in advance.
