Been getting the following warning in the logs:

warning: Invalid args to yield(); tick count must be >=0
stack traceback:
[C]: in function `WaitTicks'
...\projectiles\components\tacticalmissilecomponent.lua(141): in function <...\projectiles\components\tacticalmissilecomponent.lua:38>

The following units in the mod get this warning in testing:
Abyss Depth Charge Platform (EDC0305)
Seraphim T3 Heavy Cruiser (SHC0202)
Seraphim Storm Launcher (PD4SP2108)

The Doom units, which also fire Tac Missiles, do not get this error.

The strange thing is the Doom units (projectile DoomCruiseMissile) and the Abyss Depth Charge unit (projectile AbyssMissileCruise) both use the same projectile script and blueprint, with just a difference in health and speed. They both reuse edited Tac Missile files for UES0304 (UEF T3 Strategic Sub).

TMissileCruiseSubProjectile = import("/lua/terranprojectiles.lua").TMissileCruiseSubProjectile

The Seraphim units reuse the Tac Missile files from XSS0202 (Seraphim T2 Cruiser):
projectile StormAltMissile
projectile StormTacMissile

SLaanseTacticalMissile = import("/lua/seraphimprojectiles.lua").SLaanseTacticalMissile
