[Vinifera Bug] Runtime Error caused by Jumpjet Locomotor

[DuisPlay]

Description

Units equipped with the Jumpjet Locomotor (e.g., Jumpjet Infantry) sometimes trigger a runtime error when loading a mission if they are already on the map. The error can also occur when restarting the mission.

However, the error does not always occur; it happens randomly. So far, I've only noticed this in missions; I haven't observed the error on maps with pre-placed jumpjet units in skirmish mode.

i used TSC 7.06 with Vinifera nightly build 8732d14.

Required Code (optional)

No response

Steps To Reproduce

• Install TSC with Vinifera
• Download and install nightly build 8732d14 (the latest version of Vinifera at the time of this report)
• Start Nod10a or Nod9a; these have pre-placed Jumpjet Infantry

It's quite possible that the mission will start normally; unfortunately, the error is very random.
I recommend adding this https://discord.com/channels/338055131666972683/826473223276986409/1452842520185798718 as well: This allows you to select individual missions directly from the main menu.

Expected Behaviour

Missions should load normally without errors.

Actual Behaviour

The game sometimes displays a runtime error on the loading screen of a mission. (see attached screenshot)

Version

nightly build 8732d14
