This time you didn't change line 48. Any reason why? Are you sure static analysis is failing?

[nwnt]

I forgot about that line. Sorry was multitasking and only addressed the part you commented. I just added line 48.

For both of these, they didn't make the static analysis fail, but a warning. Would be best to correct them.

[serathius]

We shouldn't care about warnings.

[nwnt]

Should I abandon this PR and remove the same changes on the original PR?
