ZoneBuilder/Source/Plugins/BuilderModes/VisualModes/SectorData.cs
MaxED cb882a4340 Fixed, Visual mode: texture offsets were updated multiple times when moving texture offsets of several extrafloor sides linked to the same control sidedef.
Fixed, Visual mode: sidedef geometry of sectors affected by "Copy Slope" effect was not updated when the source slope was modified.
