ACM TAPS moved my camera-ready to support, deadline is in 2 days. Anyone been through this? [D]

My paper got accepted at an ACM conference and I'm doing the camera-ready through TAPS. The PDF compiled fine, but TAPS flagged a "source to HTML conversion issue" and moved the file to TAPS Support. Now the upload option is gone from my dashboard, so I can't resubmit myself.
I've already fixed the likely causes in the source, sent the corrected zip through the support form, and emailed the publication chairs to let them know. The deadline says the paper has to be uploaded, verified and accepted by the 20th, and I've read that support tickets for conversion issues can take 72 hours or more.
Has anyone had their file moved to TAPS Support close to a deadline? How long did it take them to get back to you, and did the chairs give you extra time? I'm pretty stressed about it, so hearing how it went for others would really help.
