My server is using the client provided by this link. Whenever someone hover the mouse over a guild banner from an owned castle, the client crashes. The bug doesn't happen with not owned castles and only happens with banners inside the owned castle. I don't know how to debug this issue, even deactivating the patches that ignore errors (71 Ignore Resource Errors, 72 Ignore Missing Palette Error and 234 Ignore Lua Errors) the client only closes without notice.
