Please provide any additional information below.

After additional research I found how TC's position is normally remembered: via Blizzard's default layout mechanisms, in the file WTF/Account/[AccountName]/[ServerName]/[CharacterName]/layout-local.txt

TC loses its positioning after disabling and reenabling because this file is updated upon every logout (and the beginning of reloadui) with the current position of the *current frames*. And only the current frames. As such, the moment you logout (or start reloadui) when TC is not loaded, TC is not on screen and hence its position not remembered. Next time you load the plugin again, the position is reset to default since it was a goner.

The best way of dealing with this is probably to save the location yourself in your addon settings and reloading said location at each load of the plugin.
