after Cubase 8.0.5 update: folder tracks show wrong range

this happens after some time of working in a project:

  • i’ve opened and worked in a complex project with video, audio, midi, vsti tracks

At some random (?) point, the folder tracks “region” doesn’t correspond to it’s sub tracks, e.g. when a subtrack region is deleted, the folder track still displays a region in an empty area (see pic below).
This happens independently from the previously posted issues (position bar disappears, folder tracks locked).

System:

Cubase 8.0.5 64 bit
Win 7 64 bit

Plugins:
too many to list, some using jbridge v1.6b3

PC:
Intel core i7 4790K
16 BG RAM
Asus Z97
