I'm having a serious issue migrating from my custom build of OTClient to OTCv8. My client uses the 854 protocol.
After the change, many sprites are completely misaligned or broken (see attached screenshot). Floors, objects, and walls are rendering incorrectly.
I'm also receiving these error messages from ProtocolGame's parsing in the console:

What could be causing these sprite mismatches?
