I updated Venus to v2.72~1 today and the mods I made to display tank information on the Flow Overview page stopped working. My enhancements show on the Mobile Overview page and both use the same Tile Tank.qml file. The tiles appear but the data is invalid. I have compared the original files that I modify between v2.71 and 2.72~1 and have not found any differences. The GUI isn't showing any new error messages.
If you are using the tanks display on the Flow Overview, you should probably disable it if running v2.72~1 until I can find the issue.
If it's some bug created in v2.72~1, hopefully the next release will resolve it.
