Update recast from https://github.com/memononen/recastnavigation/commit/1be9de72d87dcfdecf6bea30f5461745f7d7afe6 to https://github.com/memononen/recastnavigation/commit/740a7ba51600a3c87ce5667ae276a38284a1ce75 . This differs from https://github.com/TrinityCore/TrinityCore/commit/aa645683b8b25bfb35cb977678daf5c56c1531e6 because it includes a fix https://github.com/memononen/recastnavigation/commit/77ebf643531c90ea712b496e23c48f0b0671f43d which correctly extract tile connections when using rcMergePolyMeshes(), used by mmaps_generator. MMAPs version is now set to 5. Re-extract MMAPs using mmaps_generator , any old extracted MMAPs will not work.
