I can reproduce this both the with the attached file and from the default startup file. The

Is this issue open for contributions? I was playing around with debugging this to test out my local development setup (breakpoints etc.), and I have a small patch that seems to address it while still leaving fluid simulation in tact.
@Quantumplation-4 Patches are always welcome! This particular ticket has already been assigned to a developer though, so it might be a duplication of effort. Our wiki provides instructions how to submit a patch using [arcanist ]] or by creating a [ https:*wiki.blender.org/wiki/Tools/CodeReview#Upload_a_Diff | diff .

This seems to fix it already. However, I've never used fluid guides, so I don't know if this breaks something else...
/* Read guide cache. */
if (with_guide) {
FluidModifierData *fmd2 = (with_gdomain) ? fmd_parent : fmd;
}
/* Read noise and data cache */
@sebbas, is this fix ok?
