In #160, an attempt was made to fix a crash in QuestingData.loadData() by checking if a team existed before attempting to load it: 12488db

Unfortunately, the fix was completely incorrect, and introduced a fatal error that was triggered on startup if any player on the server had joined a team. This was quickly fixed in the very next commit (898a09), but unfortunately, that commit also started work on 1.8.9, leaving the 1.7.10 branch forever stuck with the game-breaking bug.

Since 1.7.10 is still widely used in modpacks, even though the version is no longer developed, I'd suggest backporting at least this one-liner to prevent people from stumbling into it.

if it's okay, I can make a PR based on this: 1.7.10...arancaytar:HQM:1.7.10-fixed
