Start by reproducing the crash with client version 1.4.61-V1 and inspect the server or client logs as requested. Read CardRendererFactory.shouldRenderRetro and create, then follow their callers in CardPanelRenderModeMTGO.java and CardPluginImpl.java. Done means identifying the missing value causing the NullPointerException and confirming that the affected card panel loads without the crash.
