We need a simple .blend and steps to reproduce the problem, a screenshot is not enough information for us to investigate.

Hello,

Not a problem, here is a blend file that you can use. :)
oldWarrior_2.8_issue.zip

I tried to reproduce the problem in a new file and I couldn't. It seems like there is an issue with this file in particular, but I can't figure out what it is. The original file worked well in Blender 2.79.

Thank you,

The issue append because objects with surface deform are binded to a mesh with a subsurf that is different from viewport and render.
Activating subsurf on 'oldWarrior_body' disable surface deform on other objects. It's not a bug but how surface deform is working.

Surface deform is quite effective to rig some objects , but depending how it's binded it's get disabled on the viewport ( like when using simplify) or (like in your case) at rendertime .

You may try to have two surface deform : one for viewport that is binded to 'oldWarrior_body' without subsurf, and one enabled at rendertime that is binded to "'oldWarrior_body" with subsurf activated...

Quoted Text The original file worked well in Blender 2.79.

You may have changed settings bettwen 2.79 and 2.8 because this behaviour as always been there.
