Crash when resizing a map

Does this happen in vanilla as well, or just with mods?

This ticket is invalid as it relates to a modified or 3rd party client, server, or launcher.

• Any non-standard client/server/launcher build needs to be taken up with the appropriate team, not Mojang.

• Any plugin issues need to be addressed to the creator of the plugin or resource pack.

• This site is for addressing issues related to the base unmodded Minecraft; Bukkit, Forge, Optifine, modded servers such as The Hive, Overcast, Showbot, Hypixel or any other modded system invalidates your ticket, unless the behavior can be reproduced in Vanilla.

• Additionally, if you have problems on large-scale modded servers, please report it to their site. It's probably not a bug in Vanilla Minecraft.
