I have a bug where both spears are flashing on and off. It is purely cosmetic, not affecting the way the weapon is used, it is just very annoying having it constantly turning off and on.

@StarGuy707 I'll try seeing if they work when I get the chance. The new update may have messed things up. Do you know if this could be caused by any other mods you have installed?

Log report most likely to be of use to fix the flashing spear bug:

Seems that even though you are calling "null" for the frames 3-8, the game is continuing to try to find them, then when it fails, stops and restarts the animation repeat ad infinitum.. I don't honestly know if that's the case, I'm extremely new to Starbound modding.

Can confirm it is indeed a mod conflict: restored my game to vanilla and added this mod, no flashing. I'm going through the list now trying to see if I can narrow it down.

I have narrowed it down to Ancient Arsenal: Lost Weapons:

Not sure if that's the only mod conflict out there, but for whatever reason with this mod installed, causes the two spears to switch on and off repeatedly.

@SquidgeMidget I'll try and take a look at it eventually. I'm not sure if I'll remember this, so feel free to remind me at some point.

It's a few years down the line but both spears are still flashing on and off.

@CloudCoco do you also have Ancient Arsenal installed like @SquidgeMidget did?

I did not, thank you. Will test it again soon.

@Walmart the Conqueror I've now tried with the mod installed, still the same result for both weapons

@CloudCoco That makes sense, it seems like this mod and Ancient Arsenal have some sort of conflict that causes this issue. Ancient Arsenal uses the spear animation file I made according to the credits, so that might have something to do with this.

@CloudCoco Do you have any other mods installed that add energy spears?

I finally got around to checking out the bug. I installed this mod and Ancient Armory, but I did not notice any flashing from either spear. Are you sure that this is what's causing the incompatibility?
