We have code in place to prevent this. Its been tested to work. So you very likely have another mod breaking this.
This bug is easily reproducible with full cinderslime veinhammer and obsidian blocks, mining progress resets every time overslime regenerates in any way

Just tested it in my personal pack. Full cinderslime hammer, started at 54 overslime, then mined some obsidian. Had over 70 overslime by the time it finished mining due to cinderslime restoration. No mining progress reset.
You have something else breaking it.
Worth noting, I am using Forge 47.3.0. Maybe something broke in Forge since then, but that seems unlikely to me given I don't see any relevant changes at a glance.
Did some digging, and it seems that a Forge bug fix got broken at some point which in turn affects the tinkers tool. Looking at the source code in Forge, I can see why its broken, but its not broken in my modpack, making me think one of my mods has a mixin to fix the bug.
Based on that, its a Forge bug that should be crossposted to them. Specifically, the mending fix is broken, MC-176559.
I believe its CoFH Core in my modpack that is fixing this bug, if anyone wants a workaround until the bug is fixed on Forge's side.
