After updating to DimDoors 1.5.2R1.4.1RC1-228 (from an older world which was running 1.5.2R1.3.6RC1-67 on 1.5.1), I started getting this log message every 100 ticks:

18:34:42 [SEVERE] An exception occurred in RiftRegenerator.regenerate():

Not exactly sure what is going on here (corrupted TE?) but adding a null check fixed the log spam, with no apparent ill effect.
