修复了打印含有螺旋桨轴承的航空学蓝图时，错误恢复运动结构实体类型导致的崩溃

已经写坏到世界里的旧结构不会自动修复，损坏存档可能仍需删除对应区块或 mca 文件。

如果你还保留着原始载具蓝图，那么更新版本后，就能在新存档正常打印

Fixed a crash caused by restoring the wrong contraption entity type when printing Aeronautics blueprints containing propeller bearings.

Old structures that were already written incorrectly into the world will not be repaired automatically, and corrupted saves may still require deleting the affected chunks or .mca files.

If you still have the original vehicle blueprint, then after updating to this version, it should print normally in a new save.
