Summary0007695: Tree grows adjacent to a bridge, bridge collapses
DescriptionIt seems that a tile update (when a tree grows) messes with a construction...
Also, side of a tree above the bridge (where it has been) looks "cut-off", may be random and not caused by this bug...
Steps To ReproduceTry to build bridges near live saplings that may grow eventually...
Additional InformationFurther investigation needed...

duplicate of 0009946new  Retracting bridges don't require support for construction, harmlessly deconstruct when checking support later

Do you have a save of the final state or even better a save where it soon happens? If so, upload zipped region folder to http://dffd.bay12games.com/ [^] and post a link to it here.

Are you sure there are no tree parts above the place of the bridge? This is probably connected to 0007872, "Trees growing through bridges".

Was the destroyed bridge an unsupported retracting bridge (0009946)?

Presumably the growing tree caused a "support check" and the unsupported retracting bridge deconstructed (0009946).
