Bug with cloth sim? "Number of points in cache does not match mesh."

Hi!

I’m trying to create a cloth simulation using the explode modifier. After baking the cloth it looks fine in the viewport, but not in the render. In the modifiers tab I get this error message in the cloth modifier: “Number of points in cache does not match mesh.” I’m not using a subsurf modifier in the modifier stack so that can’t be the issue.

Here’s two screengrabs to illustrate this issue. Here’s a link to download the blend file - https://we.tl/t-wsjZnUP4tJ

Any help would be greatly appreciated!

I’m running Blender 2.8 and 2.8a on Mac OS 10.15.1
2.6 GHz Quad-Core Intel Core i7
Radeon Pro 450 2 GB
Intel HD Graphics 530 1536 MB

Hi. If you do some things from Outliner also the problem appears in Viewport.
You report this by sharing the .blend file with developers.

Problem solved, I needed to apply the explode modifier, it must have created new vertices in the mesh… or something like that…
