in starcraft 1.16.1, I have a terran command center that hp is to 15000, I found HP will not be displayed when HP is up to 10000, I tested it, when it goes to 9999, it is fine, then I changed it to 10000, boom just gone. can anyone fix this ? or it is fixed already?

This is normal Starcraft behaviour, I don't think it's something that could be easily fixed.

The original staredit only allowed life up to 9999. Also if a unit has both 4-digit shields and hp the hp will be hidden until the unit is sufficiently damaged.
