Ah sorry I meant z-elevation, the zindex and elevation of the level up box is both 0, and is on layer upgrades, which is a couple layers higher than the layer map, which the bush is on, having a z index of 133 and z elevation of 0.001, but messing with that z elevation and making it higher naturally brings it above the selection.
So I think it might be a float rounding issue where for some reason it will round down to zero for me and friend 1 but round up for friend 2 perhaps. I will set it to 0 as it doesn't seem to interfere with my map anymore as for some reason we set it to be that.
Thank you, and will update when I heard back from my friend
