Comment 9 for bug 1823165

@Wayne & @all, my apologist about to late to respond.
... @Wayne, as the schematic project in the project example that I sent - is without PCB design, without the KiCad board-file, it is, all I know that the time of the suspected bug occur whenever the schematic re-opened in Eeschema.
Well, this suspected bug very randomly occurred. Sometime, in example after I opened XXX.sch, then the suspected bug occur upon I open YYY.sch. Sometime, the suspected bug occur if I open the YYY.sch in which YYY.sch is linked as a sheet in XXX.sch of XXX.pro.
We can take the example as posted here: https://github.com/kicader/MATRIX-1.4-III/tree/master/schematics/800WRMS-MATRIX-1.4-III-CLASS-H-AUDIO-POWER-AMPLIFIER-LAB-VERSION :: The 800WRMS-MATRIX-1.4-III-CLASS-H-AUDIO-POWER-AMPLIFIER-LAB-VERSION.sch is linked as a sheet in ANALYSIS-800WRMS-MATRIX-1.4-III-CLASS-H-AUDIO-POWER-AMPLIFIER-LAB-VERSION.sch; When (but not ever, it is randomly) I open 800WRMS-MATRIX-1.4-III-CLASS-H-AUDIO-POWER-AMPLIFIER-LAB-VERSION.sch from ANALYSIS-800WRMS-MATRIX-1.4-III-CLASS-H-AUDIO-POWER-AMPLIFIER-LAB-VERSION.sch, the suspected bug occur. However, sometime if I open 800WRMS-MATRIX-1.4-III-CLASS-H-AUDIO-POWER-AMPLIFIER-LAB-VERSION.sch from the 800WRMS-MATRIX-1.4-III-CLASS-H-AUDIO-POWER-AMPLIFIER-LAB-VERSION.pro, the suspected bug also occur.

Unfortunately, I still have no time to deeply inspect the KiCad source code in order to find the root cause of this suspected bug ... (Wish I can do again like I did as I post in https://bugs.launchpad.net/kicad/+bug/1304418 ...)
