I have a strange graphical issue that I have been unable to find a cause for. It is for Sweeping beams by D4RK_G4ND4LF found here: http://www.hiveworkshop.com/forums/...-1-a-180409/?prev=search=sweeping&d=list&r=20

I am having an issue getting the beam effect to appear on the first cast. It will not show up on any map other than the test map on the first cast, all variables are correctly copied.

Lightning Effect Display Bug

Someone else had this exact problem with this spell a couple years ago and a solution was proposed that apparently worked for him. When I copy in the code posted by Maker, however, I get an error saying "expected a name" and it fails.

It is correct that the variables do not exist. The post in 2014 is asking me to put in variable names that don't exist to try to fix the bug where the lightning does not show up on the first cast of the ability. I am going to guess that the spell map with the trigger has changed since 2014 or something.

Here are the triggers anyway if you don't want to download the map.

Additional information I found: This bug only occurs if the unit casting the ability is not on the map at game start. If I place the unit on the map and have him cast the ability, it works the first time. If I buy the hero from the tavern and have him cast it, it will not work the first time. Seems to work if the hero has casted another ability before it as well.

I checked the map and I did not find anything. It worked when I tested it. If you could send me the exact map, where this bug happens, maybe I can see what's causing it.
I don't know what Maker meant with the solution. The lightning is probably null, if the location is null as well. But changing the position of the location does not change anything, if it is null.
