EPZ project does not load completely anymore

[plaetzchen79]

Once again my epz file is corrupted and does not load correctley anymore.
A lot of work gone?

Something like
#151
#93

Cockpit_AufgabenZIP.zip

But these workarounds do not work in this case.
The epz file is loading without any Errors. But 3 of my pages do not load completely. A lot of elements are missing (although they seem to be in the XML file).
The preview images of these pages are showing me some Errors with utf8 and a red rectangle.
I tried to finde These Errors in the XML files but i failed.
