I checked every and all "Do not invalidate translations" checkboxes after https://meta.wikimedia.org/w/index.php?title=Free_knowledge_based_on_Creative_Commons_licenses&diff=5386370&oldid=5384979 (no doubt is possible because I did it very conscientiously) but at the next (bug 45894) edit by another (bug 46716) user https://meta.wikimedia.org/w/index.php?title=Free_knowledge_based_on_Creative_Commons_licenses/de&diff=next&oldid=5386378 all the translations have been invalidated, and (bug 44328) the translation page killed consequently.

This is causing disruption all over the wikis and may explain the major uproar on Wikidata, not always attributable to rogue translation administrators (I checked and often it was good ones killing translations for no apparent reason).
The bug may be considered blocker because it makes it impossible to understand what's going on and to debug bugs or instruct users about the "features".
