The SPRD/jatos don't work after the july 2024 update

[20k]

Hi there! SPRD's have been broken for a while and are non functional. I've tracked down the issue to the 11th july 2024 update, when "JATOConts.lua" was added to the game

When DCS is loaded, you can find the following error message in dcs.log:

"2024-12-07 19:20:50.845 ERROR   Scripting (Main): declare loadout fail, duplicate not allowed: "{SPRD}" from "./CoreMods/aircraft/MiG-21bis/Entry/Aw", original located here "./CoreMods/aircraft/AircraftWeaponPack/JATOConts.lua""

When playing any mission, flicking the two jato switches up, and launching on full afterburner, they fail to engage automatically as expected

Renaming JATOConts.lua to any other name causes that file to fail to load^[1] - and the loadout error disappears. This results in SPRDs working correctly again for the mig21. So hopefully it should be straightforward to fix by fixing the loadout naming conflict here. This may or may not be exclusive to the old slot/spawn/loadout system as that was introduced in that update, but I haven't tested this. Please let me know if you need any more information!

[1]: The error message isn't really relevant, but its "2024-12-07 19:34:24.820 ALERT   Scripting (Main): loadfile: no file './CoreMods/aircraft/AircraftWeaponPack/JATOConts.lua'"

@BIGNEWY This looks like a relatively simple one, could you help get it triaged with the devs?

Still not working. Great support for a $50 module.

Tested today with the latest updates and they still do not work.

08/03/2025 and still not working...  any news about it @BIGNEWY? I guess it can be easily fixed in a future update 
 

Temporary Solution:

1. Create a blank file named "JATOConts.lua".
2. Replace the existing file of the same name located in:
   C:\Program Files\Eagle Dynamics\DCS World\CoreMods\aircraft\AircraftWeaponPack
   You can use a mod manager for this.
3. Backup the original file before making any changes, just in case.

Pros:

• You will be able to use SPRD-99 / RATO without issues.

Cons:

• If the multiplayer server has "Pure Clients" enabled, you might get banned or restricted.
• This workaround works wiith no issues in Single Player mode

It would be nice if they fixed the cone in the engine
