On one map the damage numbers were sometimes reading “test” instead of showing a value.
Even though the option to show damage numbers was set (and I toggled it on the map to make sure as can be seen in the video linked below) it did not show all numbers either. Leaving the map and loading back in fixed the issue. First time I noticed this bug in 2000+ hours. According to Discord this was an old bug (not sure if it has the same cause of course).
