force reload of chunks with errors?

i remember a while back i was messing with the config for both the server and the client, and these issues with only lower-level LODs happened. going closer to load higher quality lods phases it out. this happened when i enabled n-sized generation and maybe one other experimental setting. i just need to reload and i think it will go away, ever since i disabled that config i dont think that new lods with these errors have loaded
