Missing capacitor

[freeone]

Hello Everyone! I noticed that my self-built mod has a larger battery drain than it used to be. I disassembled the mod for cleaning etc. and i noticed a lot of gunk collected in the bottom, and after cleaning it with Contact 60 and IPA, that i have a missing super small cap. Can anyone identify what size of cap should be there, or can i just skip it? The mod actually works. Thank you! Edit: since the picture was taken, the chip above got cleaned up and resoldered:)
