Client error code appears after latest patch

[KingMav]

The below error code appears when I attempt to logon using default and Ender's client after the latest patch released earlier today(28Feb).

The client was playable until I exited cave entrance on horseback.
Looks like it's failing to render an object, maybe village flag:

Code: Select all

Caused by: haven.Resource$ResourceClassNotFoundException: Could not find class haven.Rendered in resource gfx/terobjs/vflag(v70)

The game will still load in the background, but because the error code is present, I cannot do anything except hit close.
Latest Driver's are being used for my Nvidia GPU and latest Java update is installed.

Any help is appreciated! I haven't heard of others having this issue unfortunately.

After reviewing this thanks to loftar's guidance, it looks like this is caused by old resources finding their ways into the new clients' caches. This is likely a problem with using custom client and default client interchangeably.

The fix is to delete the cache folder, which can be found in "%appdata% -> Roaming -> Haven Launcher" and then restart the client for those on Windows.
