We did this intentionally. We do not want particles to be created, unless it compiles with retail compatible crc because of the particle logic coupling bugs.
We already fixed 3 other places where particles where coupled to logic.
You can find them by searching for // TheSuperHackers @fix The particle system is now decoupled from the logic crc
Please try to fix the particle logic coupling in SpectreGunshipUpdate instead of creating particle templates again.
The gattling targeting block was gated on the strafe FX particle template being non-null. With RETAIL_COMPATIBLE_CRC=0 the headless dummy manager never loads templates, so the pointer is null and the block is skipped, leaving m_gattlingTargetPosition and m_okToFireHowitzerCounter unchanged. A headless client then diverges in logic crc from a graphical one, and the howitzer GameLogicRandomValue calls cascade the desync further. Run the targeting logic whenever the gattling is firing, regardless of the particle template, and keep the template check only on the client-side particle creation. Retail is unaffected because the template is always loaded there, so the gate reduces to the original condition.

With
RETAIL_COMPATIBLE_CRC=0the dummy manager overridesinitandresetwith no-ops, so particlesystem templates never load. Game logic reads those pointers:
SpectreGunshipUpdate.cpp:618skips itsgattling targeting block when the template is null and leaves
m_gattlingTargetPositionandm_okToFireHowitzerCounterunchanged. A headless client then diverges in logic CRC from a regular one.Now the templates load in both modes. The
createParticleSystemoverride from #3006 is kept in both modesas well, so particle systems still do not accumulate.
The base
createParticleSystemis now unconditionallyvirtual. It was already virtual in retail builds,so retail vtables and CRC are unchanged; without it the dummy override does not compile at
