Whenever I place a Lynel on the screen I have this wierd problem. The swords it shoots are all invisible. Not that they're nonexistant, but actually invisible. I thought that they used the same tiles as the White Sword, but I may be wrong. Oh yeah, and I'm using 2.10 but I get the problem in 1.92 also.
The "Invisible" Sword
You have to go into graphics>sprites>weapons/misc and place the enemy sword
Ah, that would do it. Thanks!
