Pinned icon randomly disappears

[tetsu]

Hi,
I'm currently suffering this strange bug: Cent pinned icon on windows 10 taskbar randomly disappears. 
As you can see in the image, there's no Cent icon on the taskbar, but right-click menu from start menu indicates that it's already pinned. If I unpin, open Cent then repin again, it'll stay that way for some time then re-disappear again at some random time later. 
Cent pinned icon much likely disappears when I leave computer sitting idle, which may suggest that when Windows performs automatic maintenance at idle times, it sees the icon as being broken and deletes.
This bug is driving me nuts. Any help would be much appreciated.
Thanks!

Are you using portable version?
You can follow the instructions in readme.png, and try deleting all files under "ImplicitAppShortcuts", then re-pin it again.

[tetsu]

No, i'm using installer version. I downloaded the portable version and did as the readme says, things seem fine now.
I'll report back later.

[tetsu]

oh, it disappears again now.

@tetsu,
Have you changed the default installation path(choose different path other than AppData)?
The icon should be removed by OS after it found something wrong.

[tetsu]

No, I didn't change the installation path. It is currently
C:\Users\tetsu\AppData\Local\CentBrowser\Application\chrome.exe

Then it is quite weird.
The icon might be deleted by something.

I'm really tired of this bug, can't wait for new version to see if it's back to normal.
Cent with chromium 52 core didn't have this problem.

OK, we will upgrade to 54 as soon as possible.

Great!
Cheer!
