Clan building progress bars incorrect

After an action is completed on a clan compound, building, or upgrade, the relevant line is removed. The progress bar is recalculated taking into account only the remaining lines - i.e., after completing an action, the progress might drop to 0. In the below screenshot, the Woodcutticus Compound has had all of the Add Post to Fence, Clear Ground, and Remove Rocks actions completed, but the progress bar is showing no progress; it was showing good progress when there were still 599/600 Clear Ground actions remaining.
