From nickbabcock/boxcars#174.

ERROR: MissingClassName "TAGame.Default__PRI_Breakout_TA"

-- Context: Replay, content, Content, frames, element (0), Frame, replications, element (21), Replication, value, ReplicationValue, Spawned
-- You are using Rattletrap version 14.0.0
-- Config {compact = False, fast = False, help = False, input = Just "dropshot-replay.replay", mode = Nothing, output = Just "replay.json", schema = False, skipCrc = False, version = False}
-- Please report this problem at https://github.com/tfausak/rattletrap/issues/new
