Warning in Atlas about GetTechModifiedProperty

[Langbart]

Starting an AI simulation in Atlas throws the following warnings:

WARNING: GetTechModifiedProperty: numeric modification format not recognised : ({affects:["Unit", "Structure"], multiply:(void 0)})
WARNING: GetTechModifiedProperty: numeric modification format not recognised : ({affects:["Unit", "Structure"], multiply:(void 0)})

The problem can be reproduced consistently for the current SVN [25877] version, for A25, for A24b, but the warnings do not occur in A23b.

Steps:

• Open Atlas
• Click on Change Players
• Select AI for player 1
• Click on Generate map

Pretty sure it started with the modifiers manager in A24.

The warnings do not appear at [21945] (A23b macOS), I managed to compile up to [24278] and the warnings still appear.

The ModifiersManager.js was added with [22767], but I am not able to compile with this changeset number, I get problems with the library files on macOS.
