Yellow light splotches. Missing Cached Shader Map For Material?

Has any run into this problem before? It happened after I put a stationary light outside. The yellow splotches kept popping up as I tried to increase indirect lighting quality. The output log says this initially: “LogMaterial: Missing cached shader map for material XXX, compiling…” so my best guess is It lost memory of the cached shader maps. I appreciate any info you guys could provide.Thanks in advance
