Issue description: Storage Scanner being erratic in 1.15.2

Versions:

• Minecraft: 1.15.2
• Forge: 31.1.14
• McJtyLib: 1.15-4.0.1-alpha.jar
• RFTools: rftoolsbase-1.15-1.0.0-alpha.jar - rftoolsstorage-1.15-1.0.1-alpha.jar

I thought it might have been mod interaction, so I tried it with vanilla double chests and minecraft only items. Sometimes iron bars would show up, sometimes they wouldn't. I would see 2 items, then 6 blanks, then 12 items with wrong quantities. In the next chest 5 blanks then 6 items, wrong quantities.

Can you give me a few screenshots where it shows how the storage scanner is not showing you all information?

The double chests I showed were mostly full with many stacks of each, not the quantities showing. Both had many stacks of redstone, glowstone, lapis, dirt, clay and more.

Well in the last screenshot you don't seem to have marked many routable chests but other then that it seems indeed that it isn't working properly. I'll check it out

The chests I didn't show had more modded stuff or where modded inventories and I was trying to avoid it.

BTW is it only broken with double chests or also single ones?

Whats in the single chest on top of a builder:

I can reproduce the problem

Sorry I should have responded a week ago. You fixed it in the update right after I reported it. Thank you for the prompt response.
