Not sure whats causing it but it seems that the Mega Drone gets much bigger at times

I've seen this happen before. In the past, it was due to bugs which I was able to fix, but not sure what's going on this time. This is related to networking, so it should be resolved when you reconnect to the server at least.

ok it seems to fix it when destroyed and respawned to. It usually does it when leaving the area and coming back its either bigger or smaller.

I did some testing by going in and out of network range of the drone frequently, and restarting the server, but have not been able to reproduce the issue so far.

As for what could theoretically cause this, when the client leaves network range of the drone, the client is normally supposed to delete both the drone and its sphere parent. When the client enters network range again, it recreates them both and resizes the sphere, causing the drone to resize to the correct size (x7)... If the client only deleted the sphere (for some reason) when leaving network range, but kept the drone, then when the client enters network range again, it will recreate the sphere, which will cause yet another resize event for the same drone, causing the drone to become 7x bigger (49x size).

Since I can't reproduce the issue, you may have another plugin conflicting, or the issue may just require very specific circumstances to encounter.

If you are using the feature of Entity Scale Manager to hide the sphere after resize (looks like it from the screenshot above), that option might be more likely to cause this issue, so consider turning that off.

ok thanks
