I've noticed this issue while bot playing quark stand-alone and on a modpack. Oak chests will not open for me. single or double chests. What confuses me is that I see other YouTubers playing in modpacks with quark and they can open oak chests. Can I have answers?

(In 1.12.2)

I had the same problem. I just updated my optifine(OptiFine 1.12.2 HD U C9) , then it worked.
