There's a bug in the localizations (even the English)
The supreme commander tones strings for Science, riding and Alchemy skills are missing.
I looked in the files and found this
0x5F39FD5386317C46: Skill: Riding
0x722FA9775BA3319F: Sim will improve jumping skill when no tasks are assigned.
0x5BD5B00F71A530CC: No available actions!
0x5379CF5BC3EC7EE0: Skill: Alchemy
0x26F1163FDB025525: Sim will improve alchemy skill when no tasks are assigned.
0x08FC886BD411E93A: No available actions!
0x0F584093C924B2A1: Skill: Science
0x801094D2062BF972: Sim will improve science skill when no tasks are assigned.
0x24AA0A4AEA581193: No available actions!
Those are wrong defined,
<KEY>Awesome/InteractionTones/SkillRiding:Name</KEY> --> <KEY>Awesome/InteractionTones/SkillName:Name</KEY> (wrong format!)
changing to <KEY>Awesome/InteractionTones/SkillRidingTone:Name</KEY> --> <KEY>Awesome/InteractionTones/SkillNameTone:Name</KEY> (right format!)
fixes the problem.
The result is this:
0x75909107363BD06A: Skill: Riding
0x57B925EAD3F0C5EB: Sim will improve jumping skill when no tasks are assigned.
0x806B9764F99A38C0: No available actions!
0x2E10FF257D3F73D4: Skill: Alchemy
0x540E60B75BE28661: Sim will improve alchemy skill when no tasks are assigned.
0x2206BC2E0F1880CE: No available actions!
0xD3557F7B036DBF95: Skill: Science
0xD047DB70CA9F432A: Sim will improve science skill when no tasks are assigned.
0x4F1F040EBD0D6EBB: No available actions!
