Bug that caused the railroad bridges to become disconnected in two maps

Since the current Contest of Mayors began, the railroad bridge in Green Valley has lost its connection to the tracks, causing the stations and other facilities in the central map to no longer function.

Also, the railroad bridge just before Frosty Fjord has been disconnected for some time, which has also caused the railroad tracks and other facilities to no longer function.

When will these be fixed?

I use the Android OS．
